Pull some parts off my engine ( intake manifold for one, I notice that my block is a 302 w/289 heads, is thissetup ok ? I own a 65 auto with 4 barrel setup when purchased. I currentlyadded headers and new value covers. The intake I justhad sandblast was pretty ugly with oil and dirt. Someone told Ishould replace those heads with 351 heads over that 302 block.Both are in excellent condiition so I was not going to do anything with those until later.
Thanks

 

351 heads will open 'er up and let it breath better, but your fine with the setup you have (as long as your happy with your current power)
