X58 and X8 power pack heads

[Brandon T.]

I just got a engine for my 58 and both heads are 3748770 but one has X58 and the other one has X8. What is the difference between X58 and X8.

Hi Brandon I have not seen a head with X8, could you post the head dates. I guess it could be a casting error. Phil 8063

How are they spaced? X8 or X 8

Re: X58 and X8 power pack heads

X 8 Has a space between the X and 8

X 8 Has a space between the X and 8

That would leave me to believe it was a simple error in the core at the foundry, unusual, but certainly "production" in terms of being put into the general line of production once cast.
