Head Shaving Ques

So the max u can shave ur head is 120 thou. If i got say 80 thou taken off, would i need to do anything with the valves?(Do they hit the piston) or any other mods at the same time. Also is there some dome top pistons that fit into the g161..thats to up the compression instead of shaving the head. Anyone got any prices for both? thnx guys

shave it to the valve seats if u like, clearence probs with the valves hitting the piston will depend on the cam you are using. using standard cam u wont have prob no matter how much u take off if i recall

i have a 30 / 70 cam and u can hear it at idle and shaved head with no clearence probs, u only have probs if u run about a 44/80 cam or around that

Yah, depends on the amount of lift from your cam. You can always fly cut your pistons to suit if you wanna shave your head down heaps and have a nice long duration & high lift cam

I've got a Crow Cam in the head and its lumpy as.

On idle the car rocks side to side, i lov it.

and sounds spastic.
