im planning on putting my gsr head on my b20z block. I was wondering if i would have a problem with the valves touching. Should i just stay with the stock gsr cams for now? i have searched and only came up witha b16 head being fine. any help would be appreciated. any other suggestions for my swap?

im not too sure, i hop someone comes with a definitive answer.. But id swap them out with a 84.5mm piston with big valve reliefs to gain compression and valve relief

 

The itr cams will hit the pistons in vtec, you can open up your valve releifs with a dremel for more clearance, just use a bseries vtec piston for a guide.

 

thanks for the replies guys. anyone else have any input?
