Whats up guys. I just bought a gsr head that im going to be putting on my b20z. My question is since I have the z motor with higher compression will the valves make contact with the pistons. thanks

you should be fine but im not 100% sure on that vtak stuff lol

make sure the timing is dead on...just fyi i have a b20b w/ gsr head and .0012 off the head with skunk2 pro1's and my valves just barley touch the pistons.

i think it mostly depends on the cam lift. the thing is that the non vtec pistons have valve pockets only for a 31mm valve (vtec is 33mm)

put clay in between to find out.

Clay the motor to be sure. But with stock cams and nothing milled from the head should be fine. Larger cams can be a problem but clay the motor. Using a 3 layer head gasket instead of the thinner 2 layer will help. GSR head on the b20z has been done tons of times so I think all will be fine.

last time i checked this was a NON-VTEC forum LOL clay the engine to be sure and if u don't know what i'm talking about u shouldn't be building engines HA HA HA

Yep and Yep. Nonvtec here. I dont hate on Vtec I think it is great but this is all non 3 lob cam stuff. You will find more info on a Vtec or general Honda forum. Who needs Vtec when you have low end torque. But my track car will be a B20 Vtec build.

yah im just finishing a ls/vtec myself but back to track if CTR pistons fit in a ls block with a vtec head i dont see a problem with the b20z pistons they dont have as much dome hight as the CTR but to be sure like i said clay the engine
