Take a look at @Johnny Mac at blueprint, he has a great stroker.

Indy bore and stroke is 4.185X4.00 Mr. Garrett. That's on a 360 block. 66 Jim I think you're being generous.
The Indy heads have that reputation…. I think it would be a excellent screamer.
4.180 stroke….
Your comparing a banana to a cave man club.
He is also asking about cylinder heads more so over the stroker size.
4.185 X 4.18 = 460.54
4.2 X 4.18 = 463.29
4.2 X 4.25 = 471.05
The trick there is a block that can use a 4.2 piston in its bores and finding or making that once available 4.25 sbm crank.

I agree on caveman! But I was thinking OP was contemplating building a stroker?
could be seen ether way I guess? IDK, I seen a question on cylinder heads or the entire package as a whole.
No matter. A banana can be just as painful as club….
Depending on how and where you get hit!
If I could do it all over again, I'd have gone with the Indy 360-1 heads/intake in-lieu of the Trick Flows on my 421.
That's not a knock against Trick Flow. Their heads are awesome. The Indy heads are just more capable IMO. I'm seeing guys run high 9s N/A with them. Larger exhaust ports. They're just "gooder" for my application. Just depends on what you're using the car for.
