Hi, does anybody know what the AU intech motor included valve angle is? I need to machine deeper valve pockets into my race engines pistons and I'm unsure of the angle. Cheers

I could be wrong but I don’t think the AU has valve reliefs cut into the pistons.
Either way, have you looked into fly cutting your pistons? I’m trying to find some info on a 94dt head conversion on my AU. The issue is this head has an aftermarket cam in it so I’m in the same boat as you. If there’s any issues I’ll be making a fly cutter and going down that route.
