I have been working on my 67 6 to 8 convert. I have a 351W that is being rebuilt, I need some advice for heads. Was there a good year of heads made for that motor that will give resonable HP???
69 heads are the best year.. best CC for the windsor.. were building ares and using a set of Twisted wedge heads though.. sadly cant beat the new age stuff but then again were aiming for 500hp+
for the time and effort you are going to burn trying to find a set of 69 351w heads, you would be better off buying a set of windsor sr heads. complete they run about $900 ready to bolt on.
