While searching craigslist tonight, I came across a set of D3 heads. Ideally, I would like to stick with the c9's that I have. However, according to the listing, these heads have been fully ported with a valve job. I am guessing that these heads have hardened seats in them as mine do not. So what are your thoughts on these heads? Everyone says the c8, c9. d0 are far better. That may be so but if these d3's have been fully ported with a valve job then this sounds like a deal. He is wanting $200. It sounds a little too good to be true but I thought I would ask on here. Also, how would these change my compression ratio? Would they go too far? It sounds like the d3's are around 95 cc
See this attachment on "cylinder head comparison". I hope it is not too small to read.
