I was wondering if you could explain a little more . I need to use all 18 bolts on my build. How did you plug the holes , weld ? Did you drill though the head ?
Ill see if i can download the emails from Kent Ritter & Dave Stinson from Edelbrock back & forth .
If you have the heads check a gasket to see if the hemi style bolt holes centres line up with block centres you can remove the Heli coils from the head inner bolt holes i used a 17mm long series carbide mill cutter to help prevent flex & a lot of coolant those heads are hard .
