Hi guys and gals, I bought a set of freshened-up heads from our race team. I'd like to use them on an 11-1 406" SBC I'm building for a'53 Willys wagon gasser . They came on a motor we bought just for the short-block. Anyway, they are World Products # 12442. I can't find anything about them on the old interwebs. They have large ports and appear to have 2.05 intakes and 1.60 exhaust valves. I THINK they have 64cc chambers. Anyone know what I have?.
Call World Products. I have a similar set of Sportsman heads on the 355 sbc I am going to use in my altered and I had to call them for a positive ID and to get a spark plug recommendation. They were very helpful. Don
