i got a gsr head ready to put on my b20 block,but i'm getting different feedback from people that a b16 would be better..soooo b16 or gsr head which would be better and why?? thanx 804..

 

Just use the GSR head you already have.

 

gsr will make 0.2 more cr more than b16 head

 

Stock vs stock, the b16 head flows a tiny bit better (3-5%), but the GSR head has higher compression and a better quench area. Its subjective, but personally I would rather have a stock GSR head than a stock b16 head.

 

keep the gsr head, slap on a single runner IM(skunk2, blox, jg, etc). higher CR and better flow.

Plus, opening the chambers is cake on a gsr head.
