what you read.

No actual exp. Just from the math it'd move the in/ex valve inside edges .125" closer (starting w 2.08/1.74). If that would work w no interference you could plunge cut the walls to unshroud the rest

You don't want 1.88 exhaust valves anyways 1.81 is about as big as you would want to go.

2.19/1.88 may actually hit.

2.14/1.81 is the std oversize combo. Just wondering would 2.19/1.81 or 2.14/1.88 be better or worse

yes thats why I'm asking... I allways have known about 2.14/1.81 oversizes, but really suprised me when I saw the 2.19/1.88 option too even from MP

actually MP offers 2.20 not 2.19

I have though about a 2.14/1.88 combination too.

Not now, but in a future ( unless I screwed up porting my heads now LOL )

I have the exact set up on my 452 cast heads. Were done by Indy years ago. Still in use and flow well on my 498 stroker. Was an expensive set up years ago but you can do better now out of the box with stock alum heads at more reasonable $$$ these days..
