I have some Cnc 317 heads, stock valves that I'm either gonna use or sell just wondering how much gain would be had installing them with my magnacharger. I feel it will be minor being the air is forced jn the cylinders anyways.

 

What are you trying to put them on?

Keep in mind that boost is a multiplier of power. If you make more power NA you will make more power in the boost. The extra flow from the heads may reduce resistance and you will make more power with less boost. Heads can lower your boost and allow you to pulley down more safely.

 

Interesting...thank you

 

If they are cnc ported I would def use them even with stock valves and do studs and LS9 gaskets while you're at it! You'll be glad you did.

 

I have both of those ready to bolt in with a gt7 cam
