240 / 300 Carbed head Info

[Rmoore45]

Can someone with an older cylinder head that originally had a carburetor measure the head bolt hole clamping height? Could also be called the boss height. I have an EFI head and it measured 3.075", just want to see if both heads have the same clamping height.


Thanks,

I measured the front two passenger side holes on a 1985 300 carb head. Got 3.048 and 3.143

An LS is 1.625" since you mentioned a hybrid head earlier....
