I will be doing this during the winter. First I have to take apart everything, because my frame is rusting in spots, so work doesn't matter. I think that I will do both of them at the same time. If I have enough money, i will send my head into ct for porting I think its like $375.

 

get a 440 kit... well worth it..scrambler123 i missed the part where a 416 quailifies for a big bore?... running a 11-1 comp with 93 octane will be fine
