Re: block numbers heads

found this on a corvette site.

3991492 was a service only casting that was machined as a replacement for all earlier big port/big valve heads, so check the casting numbers again. They could very well have been used for "LT-1 crate engines".

The "2" may just not show up or be very faint.
