If it is Leo Imperial, the heads are destined for his 914... We took his top end off a couple months ago, he's got 100mm p/c's to go w/the heads.

But other 914 guys are reading this and if you look at most of the used "BUS" heads they are cooked IMHO bases on my experience. I have tried the used rebuild bus head thing 20 years ago and had problems (cough, cough dropped seats) and installed new heads at quite a price even then. Hopefully these are low mileage heads that haven't been abused in bus. Remember, I have a 77 Bay Westy that I just finished rebuilding the 2.0L motor on. Only 115k on those heads that were IMHO toasted....and recyled at the dump. Pulled studs, cracked, stripped plug holes etc....and this engine never had been apart, still factory assembled. CHT gauge reading were in the 375-400F range all te time when I drove it. Now its in the 300-350F range, much cooler. So in closing, its ok that Leo is using these but for the rest of the 914 crowd its not. (IMG:style_emoticons/default/av-943.gif) I'll buy you a beer whenever or where ever we meet up again.

WOW!!!
Let me start by saying... Thanks for posting the pictures (IMG:style_emoticons/default/biggrin.gif) I wish I could have gotten time earlier to read this post. So here is the story. The engine is the original 1.8 that came in the car - a 74 914. In 1981 the PO had it rebuilt by Garitsons (spelling???) in Nor Cal. In 1984 the engine was pulled and replaced with a stock 2.0 from a wrecked 73'. I was told the swap was done to get around smog laws that had changed after the rebuild and of course I was told that the engine was solid and had no issues when pulled. 2 years ago I bought the car and the 1.8 came with it as part of the deal. I also go paperwork from the rebuild and the reciepts added up to over 3k. Pretty big chunk back in 81' IMHO. So, here I was with a spare engine that I had been told was dino tested at 130 hp. Well that sound great, but lets be realistic. The guy could have said anything he wanted. It was not going to sway me on the purchase. I saw it as a free core. Anything more, well cool I'll take it. A few weeks ago we started on Pete's "quick" rebuild and found ourselves with the shop for the day no work able to be done on Pete's engine until he got the new parts. Well who wants to waste a free use of a full service shop for a day and 7+ 914 guys getting together for the day. I put the 1.8 into the bus and brought it down that morning and we bench tested it on the floor of the shop. It ran great. I could have tossed it in my car and see how things went, but that would have been too easy. So it is a free engine that is being cleaned up. That's it. I would love to throw money at it, but I can't. Trust me the amount I am spending goes up every day. Just like every mod "well while I am in there I might as well". It never stops. I just figured if I am going to clean up the heads why not let it breath a bit better. Port and polish turns into larger valves, turns into dual springs, turns into... relocating the plugs. Nah I'll stop here. For now. BTW - My understanding was that these were the original 1.8 heads. My bad. Oh and I would like to thank everyone for there input. I love this place (IMG:style_emoticons/default/av-943.gif) Here is the engine running for the first time in 20 years - VROOM VROOM |

B Everything I have read tells me they are 1.8 heads from a 914. Bus heads have a domed chamber if I am correct and the 914 chamber is what I would call butterfly shape. |

The combustion chamber on a bus head is smaller than the combustion chamber on a 1.8 head, so the spark plug actually sits almost in between the valves, while the 1.8 head has the spark plug location out a little more towards the cylinder.

Leo,
Apparently you should of thrown those heads in the trash. Or at least moved the spark plug location on both heads. In the one day you had at the machine shop. Oh... and do the porting and the valve job and the time serts, the cleaning and the blasting in the same day. You should not have used your free day with a bunch of bro's on those crap heads. Apparently you wasted your time and your cash As they are GARBAGE...!!! You should NOT have had the joy and the learning experience of porting your heads. Yup.. You wasted your time. Furthermore you wasted all that machine shop time. Therefore you wasted all your friends time there as well.... Shame on you Leo. NOPE... you wasted your time. Those heads are 30 year old trash. How could you not know that?? NOPE, NOPE, NOPE. Just toss em over the fence. You wasted all your money. Your time. And the joy of learning. Next time... send the money to Briitt and Bleysing and have them take care of your heads. Cause you don't know anything and you are sending a bad message of using old heads to the entire 914 club. Shame on you Leo... You must be as dumb as me. (IMG:style_emoticons/default/av-943.gif) Clayton (IMG:style_emoticons/default/wink.gif) |

If only I had bought a subie or even better a 911 with a white interior. Everyone that disagreed with me owes me a beer. No wait I can't find Casadores on the East Coast, so one of you Left coasters has got to send me a bottle. I need something good to drink as I put the engine back together the wrong way. |

Those are 1.8 heads. The reason Jake and I stay away from bus castings is because of the fatigue and cracking they usually suffer. If it isn't apparent after cleaning, it becomes evident when welding and machining.
The 1.7's don't suffer the effects of this as bad as the 1.8's, and they not as bad as the 2.0's. I no longer work with used 2.0 bus castings because of their propensity to crack from the outside of the ex. ports toward the inside of the ports. It's a very common problem with those heads. It is true that not all bus heads have been abused. The problem is that in some cases it is dificult to tell until the work is begun. At that point the customer is already on the hook for some dough. Starting with bus castings is a crap shoot. The 2.0 914 plug location is good for 10-15% more torque (and better fuel economy) than the side positon, depending on the application. The higher the revs the more the benefit, though every combo we've tested has shown at least a 10% gain. As far as improvements go it is hard to find more bang for your buck. It's is more affordable than the price listed on this thread. |
