Cool. I've had 4 Chevelles that were either 71 or 72's. So, does the small block go into the truck?
You know those Dart heads are junk.
If you don't want them I can get rid of them for you.
I have a set of 462 casting small block heads with all new valvetrain if you ever know of someone wanting them for a numbers matching setup on an old car. One is fully ported and I never finished the other. The seats and valves are already cut. The valves are 2.02/1.60 now.
