Thanks for the recommendation on me porting the indys.

The way to go is get Indy to CNC them only and get a good shop to valve job them and blend.

The Indy CNC port can make good power and most of the hand port stuff has not been that good. (Most I would call shine job ) sand roll and make you feel good about spending your money.

Water to close in the short turn to really get after this head.

If yours are as cast the Indy program will be a big improvement.

Some work on the intake will help also if it's as cast.
