I have 2.02 valves in some 350 heads on my 283 and it runs like a raped ape. 14022601...80-86...267/305......1.72/1.5 or 1.84/1.5 valves, 53cc chambers. the small combustion chamber will give you good compression-there are other 60 CC 305 heads if you are scared of compression.hese heads are made FOR a 283 and will Yeild in the 10-10.5 to 1 compression. I would stay away from all late model heads personally. Your deal is NOT a Nightmare, Just run a Stock 283 Dampner..
