BIG Turbo build planned - turbo guys!

Piston to valve/bore to valve clearance may be an issue especially if you go oversize. I'm sure you can find plenty of k1/weisco builds to get an idea.

Sounds like an awesome build can't wait to see it.

Mark has his .015 in the hole and it clears .550 lift, only grinding on the piston was due to .030 offset pins
