No, the HO heads aren't much (if any) different from the stock 305 heads. They're small valve (1.84, I think) to compensate for the small bore of the 305. Even if they flow a little better than stock heads, they'll still choke the 350. Bleeve me, I did it. I built a nice 355 and put small-valve heads on it and the damned thing went flat as a pancake at 4 grand, even with a fairly radical cam in it. I wouldn't use 'em.

350 4 bolt but I think the HO 305 heads have bigger valves and higher compression. I had the stock 305 heads on the Elky when I bought it. Ran it that way for 8+ years. When I blew a head gasket and put 350 heads on it the compression went way down and ran like puke In comparison. I think it will be better than what I have unless there are flat tops in there when I open it up. I already run premium to keep it from pinging. So it packs a punch. Just smokes real bad when it starts an it is real embarrassing. Plus I don't want to wait till the coolant and oil are mixing before I do the deed. JC.
