CNC Porting- The Best?

[Pete]

To get the best performing heads could be done but would cost time and money.

We would probably need a couple sets of heads, flow bench, engine dyno, gaskets, lots of labor,etc.

Flow bench doesn't always tell the whole story you do need to put it on dyno.

All of the above still does not guarantee you will get better then what we have now.
Lets just say we do all of the above and gain 3-4 hp would it be worth/cost affective.

I have spend lots of money and time on cam research trying to get the most out of a LT5 350 we did discover a few things, now can there be more power in cams? again goes back to cost affective.
