1st gen B16a head on B20 crvtec

Are there any problems with using the head from a first gen b16a when building a crvtec engine. Most B series engine parts are interchangable?

You need to get the compustion chamber on the head machined out to match the larger bore of the B20.

Thats the only real problem I can think off.
The problem being if you get it wrong the engine will never work properly.

i have a b16a1 head on my b20 and it runs fine.

Well if you didnt get the head machined before you stuck it on, then it could be running a lot better. :D

the head and the block need to be machined for the swap to work. so yes mine is machined

The serious problems I know you could have would be if you advance your intake cam timing too much (past +3° or so) the valves can hit the piston, that causes large problems. Reference www.crvtec.com
