I just grabbed these puppies out of a van in the junkyard, the old 305 was in the cargo by, and the new, crate 350 was in place, heads are BEAUTIFUL, and better still only 40/pr. btw, these are centerbolt. the full casting is 14102193. mortec only says 87-95 350
thanks fellas. mike

 

Yup, those are 1.94/1.50, 64cc heads for use on 4.00" bore.

 

thanks man! makes life that much nicer today. we actually hit them by accident, making fun of the sludged up motor in the back, and my buddy is like "hey, look at this" makes me wish i would have grabbed that motor for $75 more
thanks again
mike
