From what I've read and who I've spoke with it seems that TEA, PRC, & AI are my best choices for porting my LS6 heads, but how the hell do I decide who to use. I know i'm not the first to ask this but what does everyone think?

 

??????????????

 

Talk to some INDEPENDANT dyno shops and see what they like. Hang out at a few tracks and see what the fast guys are running if they will tell you lol. Lastly check out the dyno section on here and throw out the high and low #'s and see what most people are making... You have a couple really good choices listed.....

EDIT: Ohhhh....and throw ADVERTISED flow #'s out as their importance is often overated and most likely inflated in the real world anyway...

 

There's several good head machine shops doing LS cylinder heads. We do complete cnc porting, cnc valve job & full reassembly & decking for a very very reasonable price. We charge $750 to do every step of the process from start to finish for you!

 

I have always used TEA, they are very good and have always given great customer service.
