So, I have a mismatched set of heads on car just purchased 1) casting # 3782461 date# D75 2) casting#3890482 date# D76
Have 1) figured out but can,t seem to locate 2) casting number, Only reference I find are on a few forums on internet. Any idea on 2) casting? What is it? And no I can't change 8 to 6. Enlarge numbers on computer its definitely an 8

You sure it's not 062 common mistake it appears... https://www.stevesnovasite.com/forum...d.php?t=431386

 

Do you see an 8 or a 6, Compare with 6 right below it.Are the 8 right before it. Let me know what you all see?462 or 482.

 

I think it's a 6 it looks different than the 8,possibly a minor flaw in the casting that makes it look like an 8.
I would bet that's what you have given the link I posted above where someone had the same issue and the fact that none of the charts show that number ending with an 82.

 

462. It's definitely not an 8 when you compare it to an 8

 

Thanks guys for the help! Really appreciated. So going with 461 & 462 which after reading are near identical. Takes a little worry away thinking I need to swap out heads right away. Now assembling parts for a set of 041 castings to at least get correct heads that should be on the motor in car.

 

So' finally pulled heads and surprise 2.02 & 1.60 valves in both heads with minor port work and polished combustion chambers. Camel hump heads, Any one in market for set of heads? Going back to date correct heads with bolt holes in front for 69 SS 350 Camaro.
