Head identification question Okay all you head gurus out there, I have a question for you guys.
I picked up a set of LS ported / polished heads at a local swap meet for cheap, I mean cheap ! I was told they were #243's.
So my question is: All the quick identifying casting numbers have been ground off.... EXCEPT for the 4 digit cast number inside where the valves are.
That number is 1240.
Can anyone tell what heads these are ?

I may be wrong , but I dont think those #s on the inside are going to help much I think they are just casting date . I have couple sets of 317s there date is D286 they off a 06 and the others B024 off 04. The D ports could have been ported in, have you measured those intakes they look huge.

Yeah those intakes look ******* huge, the exhaust valves look larger than stock but may not be. Someone took stock heads and put as big of valves as they could possibly cram in there, they should flow well at the very least.
