Those 305 heads were likely chosen to get the compression up a bit.

Don't go too big on the cam. 283s like less cam. Being 60 over is probably why it runs hot when hitting higher rpms.
Crusty Biscuit, my 65 c20 ran hot when going down the highway, and it had a 3 row, shroud, and good fan. Plenty of air flow, just ran hot down the road.
My old 65 c20 Mean Green never went above 1/4 from "C" on the gauge, but it had a 4 row.

Yes we used to bore them .125 over in the early 80s and called them 301s not realizing that made a 4 inch bore and basically a 302 like the early Z28s

I've heard of 283s being punched out that much, but I think it also came with overheating problems.
