I have a set of lt4 heads that im looking to do some porting on, who ported your heads ? what the flow after porting?

Already checked that but that isn't the flow that im looking for, i need some info for the flow and they don't have it

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

Katech $499

Its not about the price, i want something with info and some valve job, katech is flowing good air with out the valve job, but since im going to port then i want the best flow out of them

we use LME for our LT1/4 heads.

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

Can you post the flow on lower lift rate? Because my cam will not be at .700 anywhere, i need some info

black_c7

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

Cordes Performance Racing

never used tsp for lt porting.

black_c7

What about the flow rates ! Does it mean they are better when they flow more!

Cordes Performance Racing

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

black_c7

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

Cordes Performance Racing

no, it's not like that.

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.

FYREANT

If you're referring to the stock heads, no, they are actuslly not that good. LS3 heads flowed better..

black_c7

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?

black_c7

Fyrearnt do you like your tsp porting?
