Re: BEST STOCK SBC HEADS?
If you've got dished pistons, the 305 heads might be worth your while, they'll bring the compression up nicely. Might want to get larger valves put in them, but a little port work etc would go a long way on those.
The 113 heads are corvette aluminum L98 heads, I very much doubt you'll find those. Your best bet is some 083's (L98 heads) or 062/906's (Vortec heads).
Dont expect to find any of those, though.
I actually use my vbgarage!
