Head flow on exhaust side? Comparing at companies TEA LS6 stage 2 and 2.5 and PRC 2.5 heads.
Flow numbers on the intake side are close within each other. But the TEA's really run up on exhaust flow side. Anyone care to elaborate on why this is?
Does TEA port the exhaust side and PRC dont or is it in the matter of how the heads are tested?

It is probably how they were tested.You can't compare exhaust flow without knowing if a pipe was used on the exhaust port or not.A pipe will increase the numbers.PRC states no pipe .TEA doesn't give any info with their flownumbers but I think they do use a pipe.Lots of companies do.
Exactly correct. PRC does not use a pipe for the exhaust flow numbers. I have seen testing though on this and you'd be amazed at the numbers that can be produced/altered by playing with pipe size and length used!
