351 w heads question
So today when I went and picked up my cobra intake manifold I got a pair of 351 Windsor heads with it for only 100 more bucks. The heads have got double valve springs, new valve guide seals. All work done from a machine shop and the heads were decked. Only about 20k miles on them since then. My question is I'm building a 302 with a cobra intake, b303 and I was think gt40p heads. Don't judge me, but would it be better to use the 351 heads for my build. Or stick with the gt40p heads? The heads have dl8 stamped on them.
