I'm looking into using an ST170 engine, basically, cause it's got better headwork, conrods etc

Now all the variable stuff will be binned, and I'll be using my WeberAlpha throttle bodies & management.

Now, I want to know if normal S3 zetec cams will physically bolt into the bare ST170 head, as I can't use my current S1 Zetec cams in it, and would also like to go to something a little bigger than what I'm currently using.
