Getting ready to order a new top-end for my 914 and have a few questions. Based on my engine number and heads this is a 914 2.0, correct? I just do NOT want to order the wrong parts. I am worried the last owner might have used the incorrect parts. Thank you as always for your help.

Not 2.0 914 heads, they would be 3 intake bolts.
What's the number off of? Comes up fan shroud which doesn't help you.

Just noticed the rockers have hydraulic cam spacers, so there's a chance it's a bus engine, but you won't know for sure till you pop the heads off.

I think I found the correct engine number on the block. So is it a 1.8? Thank again for your help.

Pull a lifter out and see if it's hydraulic vs solid.

Wow, thank you so much. Any idea how my 914 ended up with a VW bus engine? Looks like the 1.8 bus piston kits are less expensive. Any advice on what piston kit I should order? I would love to get a little more performance. Thanks

Order 96mm flat tops for a 1.8l 914 as you have 66mm rods so you need the ones with the right wrist pin height. Those heads atleast have the bigger valves than the 2.0l bus heads

Many get caught like that,common enough,your heads will have small valves so unless you change to 914 type you will have limited potential,go to 96mm barrels and pistons if doing top-end build and gain a small power increase,get the higher compression ones as bus ones are like 7.3 to 1 to handle the load they push along.
