does anyone know where i can get my npi heads ported so they flow better? is it even worth it, should i just buy pi heads? i will be purchasing a kenne bell supercharger in the near future. i know the pi heads will increase my compression by 10:1. is that enough to cause problems w/ the kenne bell?

If you are sure you are going to blot a KB on there, I wouldn't do the swap. If you do, you will have to lower the compression some way or another. Not worth it IMO if you are getting blown.

The PI Headswap will put you at roughly 10.4:1. The KB and your engine will not like that.

Keep your heads...

www.steenracing.com has a pretty good rep at porting the NPI heads from what I understand...
