Different heads?

[Westislander]

I was just looking at my heads and noticed that the casting marks are similar but not the same… I think I might have 2 different heads on the same engine…. I’m not sure but is that allowed

Pull the valve covers and compare the casting numbers.

There different castings that are similar enough to mix on big blocks but I still wouldn’t recommend it. Not sure that applies to small blocks.

So I’m a dumb ass, the heads are the same- 333882… not great heads but they will have to do for now
