I had TSP port mine. I'd have to look up the flow rates but they were exceptional.

That what im thinking to do, tsp has good flow numbers and good pricing also, but more air flow is better always

We played with different valve jobs and were not able to get any more out of them.

Is it worth the money compared to tsp? Is there going to be a big difference between them?

flow doesn't always matter, velocity is extremely important.

So make sure the runners are polished ? I think that will help with some velocity

flow isnt everything and polishing does zip,

your in northridge? Try WCCH they are closeby, Mamos not far either

Dont get too hung up on flowsheets and dyno numbers; those heads are decent out of the box so its going to take someone who really knows what they are doing to do them right.

Already called wcch, they don't do them yet, idk if mamo does them will give them a call, so if not the paper and flow numbers are the things that i need to consider what should I consider?
