Buick 430 heads cracked, need help

[born2x]

Existing head casting # is 1231109 out of a 69 Riviera 430 are found to be cracked, just got a pair out of a salvage yard from a 68 430, head casting # 1382985. I need feedback to know if they are compatible before I move FWD on the rebuild. There are some variations that I see and it seems there is 1 less water jacket hole.

Appreciate any comments or info

Thanks,

Richard

Assuming our chart is correct, there shouldn't be a problem, in fact they should be a nicer set.

Thanks for your time Bob, confirming what I was hoping. I'm under alot of pressure over here, if its not one thing its another with this project. Although it is very rewarding. I was just out cleaning them up , pulling the valves and I noticed that both intake and exhaust valve guides have seals. My original head had seals for the intakes only as the exhaust guides were taller.

That means the have probably been worked on as the 430 only had intake seals.
