I though my 255 heads would have came with some flow graphs of these actual heads on a 4.065" bore at least but came with nothing. do they flow test each set before they go out?

Yer mine were through TEA and I thought they would but when I got mine, Mike left halfway through, maybe that had something to do with it.

I have a set going on a low comp nitrous motor. Here is a PM from my porter with flow numbers.
"Im really pleased how these turned out....I got back home at 2:45 AM after flowing your heads and putting custom valve jobs in a few other pairs of heads I'm working on as well....it was a long night but flowing your heads was the highlight. You need to keep in mind that we milled a fair bit off them which always reduces flow numbers a little bit....sometimes more than a little bit and i also flowed them on a real world 4.060 bore to better simulate your actual bore size (the numbers would have looked better if i used a 4.125 or 4.155 bore).
Anyway....here is where we ended up
Lift.......Int.....Exh
.200....151....122
.300....232....176
.400....298....220
.500....345....240
.550....362....247
.600....387....253
.650....393....257
.700....394....260
Exhaust numbers are tested with a 1.875 flow tube thats shaped just like a conventional header.....same tube I use on ALL my SBC testing.
