Smallblock Heads Help

This is not a short rod pos chevy, and combos are combo's...

I think our opinions are closer than you might imagine......I disagree about gasket / port matching and I never said or implied that valve size controls velocity.....the small seat / bowl , port that comes with the small valve would have been more accurate , but I figure one goes with the other.
Very stout numbers by the way........and I did learn from your post.
But when it comes to comments like the quote , I have to scratch my head.
Chev's have relatively short decks and low cams , LA MoPars have horrible valve train geometry and pushrod angles that severely limit our options from a performance standpoint.
I am fairly new to the MoPar thing ( six years ) , but I have had a bit of experience with motors of all kinds.
I can't recall ever making a statement like that since about tenth grade , and that was in 1973.
I don't think the motor knows who's name is on the fender.......there are variables specific to each brand.
But there are far more similarities , and I bet you know that too.
