I tried to do a search but I couldn't find anything really. So my question is for an ls/vtec is what head should I use for an all motor daily driven car. I heard the GSR is better for all motor because it gives a better compression, but at the same time I heard they can have a problem leaking fluents. I heard B16 is the better choice, and it flows better. Keep in mind I want to build an all motor, daily driven car that can hit 13'2 and low 12's.

 

I might be wrong but I think a GSR head would give you higher compression while a b16/c5 head would flow better. So then by my logic, a GSR head with a valvetrain upgrade and P&P would be your best bet. But then again I might be talking outta my ***.

 

i believe stock vs stock, the gs-r flows better, do a search, there has been plenty of threads/arguments on this topic

 

i would go with the gsr

 

i say b16 because it is waaaayyy cheaper than a GSR head

 

Get the P72 GS-R head.

Higher CR and a better angle for the air flowing inward will probably make more power than the PR3 B16A head.
