nop the block is bigger
YES, Direct bolt on.
No, a VW 8-valve head will not directly mate with a 1.8 20-valve turbo block. The two engines have different designs, bolt patterns, and dimensions, making them incompatible. The 20-valve head is specifically designed for the block's architecture and requires a matching head for proper fit and performance.
No
yes it will
no
press fit
They will fit on every small block engine from 1987 down to 1955. You will have to install a PCV valve in 1 of the valve covers. Your choice on witch 1.
No.
yes it will fit.
Yes you can actually fit a few different heads on. easiest is the gsr head of the same year.
Yes a d15b7 head will fit onto a d16y7 block. The Y7 engine is a later model so it is recommended to use the later model computer system.
While the head will bolt up to the block just fine, the problem is that the EGR valve assembly and sensors are all slightly different, requiring quite a bit of converting. Whatever you do, don't try to run the engine without a properly operating EGR valve; it can cause serious damage to the engine.
