Which Vortec Fits
Which Vortec heads fit older SB Chevy motors? I'm thinking pre '86.

Sold what was left of it for $800 to a guy who came to pick it up at 11:00 PM with cash in hand. Hmm. '79 Sierra Grande (Black) organ donor - perfect rebuildable 4-bolt 350 and a good TH350. '76 Sierra Grande (Orange) - hate isn't too strong a word. Kid who bought it turned it into a hot rod. '68 C-10 R.I.P. - Dad's old truck...too far gone to resurrect. '59 C-50 - with hoist. Truck is gone, wife isn't. Nuff said. |

all heads small block heads will bolt up to the block. the diff. is in how the int. bolts up. TBI heads (early vortec) have same bolt pattern as all carbed intakes but the 2 middle holes on each side need to be opened up to allow for the different angle of bolts. the later vortec heads have an entirely different bolt pattern as they only use 8 bolts. with these you have to use an aftermarket intake which is available from many sources like Edelbrock. for reliability reasons & thicker castings I suggest the later ones ('96ish & up)
