Just got my LS block back and its all done. Stroked to a 2.0, sleeved, 12:1 Arias pistons,eagle rods, balanced crank, etc. The issue Im having now is decidind what head to use. I have my GSR head that got a full race port and polish and milled 20 over. I was planning on using that but some people are saying to use a B16 head instead. That cause the GSR head is milled ill never be able to drive my hatch on the street due to the compression being raised higher than 12:1. Gonna get ITBs but need help deciding what head to use. Whats going to get me the most power and still be safe? So with this set up go with my GSR head thats done or go with a stock B16 head??

Thanks for the help

 

Good tuning can allow you to run higher compression on pump gas. How much is the GSR head milled?

 

milled 20 over

 

rocket, chime in!

or PM him..he's got some ideas with the gsr head

edit: i have a complete 99 b16 head for sale haha. let me know.
good luck with ur build

 

So say I do the race port and polish and all the other good stuff that I got done to the GSR head to the B16 head, Which is going to get me the most power?? I could use a thicker gasket on the GSR head but will it still out perform the B16 head??? This setup is still gonna be street driven but not really daily.
