351 windsor heads on a 302 - info please

[347 Stroker]

Jmarsey thanks for the link. Thanks to everyone else also, I enjoy learning more about this sort of thing.
Ok, here's another situation. Suppose I just stick to a basic 302. Some friends who know a fair amount about building engines suggest I stick with a 302 (bored over to whatever it ends up being) for simplicity and not over complication since this is my first build. If I just stick with a 302 build, would the 351 Windsor heads be ok without any expensive porting or any serious valve work? These heads are the older ones, they have the tapered rocker studs with the slight shoulder, I believe. As I mentioned, the heads are bare, so they need to be built with everything. What kind of output could I expect with the 302 and 351W heads and a mild to lumpy cam? Approx how much would it cost to put decent components on the heads, ie springs and roller rockers? Will the older heads work with my '91 roller block? Are there any modifications needed to mate a 302 intake to the 351W heads?I'd really like to do a decent build while not draining my wallet, which I could invest in restoration. Thanks again fellas!
