I definitely don’t feel you can compare numbers from different benches as “apples to apples”.

That being said........ the intake numbers look pretty decent...... the exhaust is a little weak.

Is that with the supplied valve job, or after some tweaking?

What did those cost again?

Have they ever tested an ootb RPM head for a SB Mopar, where the numbers could used as a comparison?

Heads do not come with valve job.....shop performed 3 angle valve job...no other work

Price for both heads were 1012.00 bare
