Got my heads flowed today For those who don't know, I bought a used set of Absolute Speed Stage II 5.3's from a member on the board. (I am aware of the current situation with Absolute Speed, no comments needed). Allan @ FMS then took them and worked the bowls where he saw room for improvement to help the exhaust side. He also port matched the 90mm intake. Steven at TR (SAR2K) did my exhaust port/combustion chamber polishing, and did an excellent job.
Here are the numbers : (exhaust flowed with no pipe)
Intake --------- Exhaust------ Exhaust (pre allan)
.100 68-------- 59 -------------58
.200 135--------109-------------108
.300 196-------153-------------149
.400 244-------186-------------165
.500 277-------211-------------178
.600 299-------224-------------196
.650 293-------227-------------205
.700 290-------230-------------206
As you can see, Allan's porting did WONDERS on the exhaust. Special thanks to him and Candy for helping me get all this together, as well as Jason99T/A for flowing the heads and doing the install when we get a chance.

Smart move having Alan clean–up your heads and match porting the FAST intake.
Your car should put down some go numbers.

Yep, the intake flow #s are typos. He listed the .050" numbers. Here are the correct #s:
.100 68
.200 135
.300 196
.400 244
.500 277
.600 299
.700 293
Intake port was flowed with a radiused entry
No pipe on the exhaust
SF1020 flow bench
3.900" bore
.100 68
.200 135
.300 196
.400 244
.500 277
.600 299
.700 293

What size valve's were used on those heads? And did you get the original flow sheet from the original owner or any #'s. Just trying to see if his #'s were legit!!

your numbesr on thunder bench are very similiar to ones weve found on a local bench with 2.05 absolutes Id like to know the before and after intake and exhaust port ccs... we didnt get a chance to cc his abs heads... and Id like to see how big the exhaust was when done, I dont mind big exhaust ports (done right)
