Hi folks,
1965 GMC 1000 with the original 230 L6. Pulled the engine to rebuild, and the machine shop tells me there is a crack by the #1 cylinder and I need a new head. They said the supplier they work with for remanufactured heads can't find any 230 heads but have some 250 and 292 heads. Said the remfg'ed 250 head including new springs, valves, guides, etc, (ready to install) is going to run about $500-600.

Is there any reason NOT to put on a 250 or 292 head onto my 230? Is there another source for a remfg'ed 230 head for about the same cost?

Gotta get back to the guy ASAP so hoping for some quick advice! Thanks all
