406 sbc block Ported double hump heads I have a 406 sbc block here that needs a hone I bought it for a project and never got around to using it. I'd like to get $250 for it.
I also have a set of double hump heads that are worked pretty good. They have a lot of port work done to them. I believe they have 2.05 intake valves and 1.60 exhaust valves. They have double valvesprings installed on them. They were on a 383 in a 3000lb car pulling 11.90s consistently.
