1.74 exhaust valve would not be small block.Small block or big block.... There are 915's for both...
I'd say. Put a little more with it and you have some new aluminum heads.Thank you. I'm looking to buy a pair and there is a person on ebay selling the pair I described. They are complete but need to be reconditioned. He's asking $900. I guess that is probably too much!
I have sold several pairs of good core 915s for $350 to $400 in the last 6 months
It's hard to find late 70s heads like that. lolThere are several stock eliminator combos early to mid 60's
that supersede to the 915 Big Block head and it is
hard to find a nice set that have been sitting for years
and do not have sunk valves and beat up seats.
It's all about exhaust valve size (1.60 vs. 1.74). Any 915 can be machined to accept the 1.74" exhaust valve. The rest of the head is the same.Are these just 915s or 67 915 HP heads? Sorry, Im new to big block and curious?
My fresh built HP 915 heads
