Vortec heads is there a difference between 350 and 305?
Ive been searching for vortec heads for my 305 and the casting number ive been told that will work is 12558060. They are 1.94/1.5 with 170cc. Is there a difference between a set of vortec heads with the same intake/exhaust of a 350 engine. Would that even bolt onto a 305?

the ending digits for the casting are 062 and those are from the L31 350... they will bolt right up to a 305

350 heads have larger chambers which significantly affect the compression ratio.
