I found somebody selling 210cc aluminum procomp heads, ported, with victor jr valves and springs. Zero miles on them. The guy sounds like he knows what hes doing. I heard pro comp is made in Australia, ad they are copies so are they still worth getting for the cheaper price?
The ProComp heads aren't copies of anything. They're originals and made in Australia. There's nothing wrong with the quality AFAIK but the flow numbers are nothing special. In any case, 210cc heads are much too big for a 302. They'd be more suitable in a 347.
