Hi guys, im running a fully built gsr head on my B16 build. Is it worth getting it flowed as its stock at the mo? Going for an AFI street turbo kit, got eagle rods and wiseco pistons in the build. Not sure if there is a good gain for a streetcar in headwork? After 250-350whp, cheers

 

so you want a before flow chart then get an after to make sure the port work was done right

 

Yea but does it make much diff for a streetish car, not a DD car but dont wanna kill it and make it a drag only car etc..
