I just built a 440 stroker and I used 440 source CNC'd heads. For roller rockers I would say get good ones, Comp cams pro magnums are the ones I would use.

Are those the only cylinder heads you will consider?

I used 440 source, and they were almost a bolt on.... I had to grind most of the push rod holes for clearance. Other than that they worked fine.
I did change springs after a season of driving ( only about 500 miles ) as I found one of them to be weak when I did a pressure check on the springs. I was, at the time, trying to find a top end "miss" I also did other things and now no miss, so I cant say if the spring caused it, but it was "under speck"

To be clear, I am satisfied with the heads, especially with the cost, but, they will need a little work.

just my 2 cents

I like the price tag that's why I was looking at aluminum! If there is anything in that range that's good let me know your input thanks
