I think mine are next up. Let me know how they look when you get them. Starting to get excited but still lots of work to do before the 914 hits the pavement.

Congrats....I came pretty close to ordering a set , however the $ added up quickly since I have a 1.8 which I figured the cylinders would be too small so I'd have to invest (buy) 2.0 P/Cs and then buy a 2.0 crank w/rods.

Here they are in all their glory, well worth the wait. Now, to get the motor back together and back in. Thanks Len!

Nick got his 1st. I just noticed there is not any studs in the head. Going to have to find new ones for the exhaust, intake and rockers. Going to have to check out Bel-Metric.

Stock 2.0 valve size 42x36
Mark - Len included a stud kit and a block off for venting or a vent tube if you want to go that route. |

I have a 1.8 which I figured the cylinders would be too small ... The 1.8 cylinders and the 2.0 cylinders have the same OD. The ID is only 1mm different, too. You could have used them, though I don't know how different the combustion chamber sizes are, which could have a huge effect on the compression ratio. And you'd have to deal with the intake and engine tin and such. --DD |

Per the factory spec book:
1.7 heads have 51.1cc to 52.6cc combustion chambers. 1.8 heads have 52cc to 53.5cc combustion chambers. 2.0 heads have 58.7cc to 60.2cc combustion chambers. So with a stock 1.8 bottom end and stock 2.0 heads, the compression would drop significantly. Jim |

Congrats....I came pretty close to ordering a set , however the $ added up quickly since I have a 1.8 which I figured the cylinders would be too small so I'd have to invest (buy) 2.0 P/Cs and then buy a 2.0 crank w/rods. I started with a 1.8 and just upped the P/C to 96mm IIRC, kept the 66mm crank and 1.8 rods.... 1911cc with 2.0 heads. Or in my case the valves are 2.0 size. I like mine. Saved me alittle $. |

I'm very pleased that everyone in the GB went with the ceramic coating. There is still much that's unknown about these Chinese castings, and with what we know about the more sturdy AMC castings and the benefits of ceramic in protecting them I feel it was imperative with the AAP's.
One thing to keep in mind about the ceramic coating, it's extremely chemical and heat resistant, but it is not at all abrasion resistant. It scratches and scuffs very easily, so be careful with sharp objects, and if you want it stay pretty don't touch it with oily fingers. It stains easily, though the stains do no harm.

You'll like that combo match it with 2.0L exhaust !! (IMG:style_emoticons/default/aktion035.gif) |

You're welcome Mark. Hope everyone is happy with their heads. I expect the last of them back from the coater in the next week or so.

Life's been good to me so far..... Group: Admin Posts: 15,368 Joined: 11-September 03 From: Hurst, TX. Member No.: 1,143 Region Association: NineFourteenerVille |
Per the factory spec book: 1.7 heads have 51.1cc to 52.6cc combustion chambers. 1.8 heads have 52cc to 53.5cc combustion chambers. 2.0 heads have 58.7cc to 60.2cc combustion chambers. So with a stock 1.8 bottom end and stock 2.0 heads, the compression would drop significantly. Jim Stock 2.0L crank and rods with 1.8L heads makes for a bump in the compression ratio. Put 2.0 valves in the 1.8 heads, and you make up for the non-optimal plug location issues with the increase in compression. Plus the 1.8L heads don't drop valve seats like the 2.0L heads. If you do it, make sure you run premium gas all the time. (IMG:style_emoticons/default/driving-girl.gif) |
