Looks like they worked pretty well. The intakes look a little sunk though. Are you running 2.19 intake valves? Are you running these on a 454? You are going to lose a lot of compression, are you changing the pistons too? Also what size/offset rear wheel and tire are you running? Looks like N50 15s?
Tom, I believe these heads have the original valves and seats although I didn't check yet. I think they are sunk in because they were not set up for unleaded gas??? As stated in the original post...they need to be gone through/rebuilt.
The motor is a 396 .060 over with 12 1/2:1 slugs which I didn't find out until I took it apart. I'm still undecided on what motor I am going to use. This one needs to be bored to .070 so I am contemplating putting a 427 for it since the cost is about the same.
The wheels are original Ansen Torque Thrusts. 14X6 front and 14X7 rear. F70-14 and L60-14 respectfully.
