I tend to agree with this and siting another example~ Roy/Laz ran 9.60's (actually probably closer to 9.50's considering they ran 6.0 @114mph in the 1/8 on the last outing with the old iron headed 109) in TSM trim with Champion CNC ported iron heads that only flowed 200CFM on the intake...
Hell, look at how fast Dusty has run with 23* heads on a SBC...![]()
My SBC Brodix Track 1's flowed 317 so I'm impressed by 300 from these TA heads. My exhaust went 229 on the exhaust so IMO opinion these TA need to go more than this to take advantage of the intake flow. I ran out of time for testing but it seemed my heads or headers were to restrictive on the exhaust side and I couldn't get it out of the cylinder. It's been a while since I flowed a Buick head but seems the exhaust is pretty good so it may flow enough to really see some power from these stock type heads.
Blazer. I'm no map reader but I would think that because the turbo is moving the same amount of air at 16# with good heads as it was at 22# with decent heads you will not see any downsides.
