Default Re: 1959 Pontiac 389 tri power HO engine

I think I might have a set of those heads. I've had them stored in my core rack for 25 years. They have a different water passage on the intake side than later model heads. This is form my old memory.. new have a round port and the older have an L (dog leg) shaped opening....What is the casting number & date code you need?
Monday I pulled apart a 1960, or might have been 1962, 389 for a customer that is doing a restoration. Looks like it sat around with the carb off and water made it's way into the cylinders.Stuck so bad we had to pull the crank with the pistons stuck in the bores. We drove the pistons down and bead honed the cylinders before being able to driving the pistons out. What a mess!!. It was interesting how the torque converter was attached to the tranny. Let me know on the heads...
