Curious about AAR/TA Heads

Oh....... it wouldn’t surprise me one bit if that type of test was done “back in the day”.

There are plenty of people who like heavily porting OE iron a lot more than myself......... but for me, the biggest hurdle for big flow out of J heads is the SSR.
They go turbulent, then the numbers start backing up......and I haven’t found that more area at the pinch cures it.

So, I’d be interested in seeing if the added area at the pinch showed improvements on the dyno that I don’t see on the bench.
