General consensus on who is doing the best headwork for big HP turbo builds? I'd like to send out a virgin B16 head out to for full port/valvejob/full rebuild. Head would be going on a sleeved ls/block. Not sure what turbo, something good for 700+

 

Heh. The most popular company now for doing this is 4Piston. But I'll move you over to the Drag Racing section so you can get your consensus numbers.

 

4PISTONS, Port Flow, BZE, Victory are some

 

+1 on this list. I have a port flow gsr head on a sleeved ls block, car made good power on motor and will be on dyno soon with the turbo, gotta finish the turbo kit. my next head will be a 4piston head.

That's just like rlz. Low and behold nothing to see and no one to talk to. Man go 4 piston and don't look back.

 

For a turbo you can't go wrong with a precision 6266 which will do 700+ easy. As far as the porting goes save the money and throw it into the fuel syrstem. We make around 800wheel hp stock port head, stock valves, 81.5mm CSS lsvtec with gsr head and skunk pro1s.

Airflow at that power level doesn't seem to be a bottleneck and while it would spool faster and probably make a little more power up top it's primarily a drag setup so I'm not woried about lag and the transmission is already at its limit.

If you have an unknown condition head definitely go through it and make sure it's good to go. You are going to get more bang for your buck doing a 3 angle valve job from any of the above mentioned head builders.

 

4p if customer service is paramount

 

I second this!!!

 

 

I went with Performance CNC, really good work.

 

Gen1 cast wheel journal beating making 800wheel . $900 haven't blown it up yet haha

 

That is easily one acceptable example.
Hell, even an "old school" Garrett T67 can do it.
