FREE Shipping Lower 48 States !! Used set of Original 1971 Pontiac 96 Casting Virgin Heads with ALL the Exhaust Bolt Holes Drilled & Tapped. I started disassembly on one head so I could order the correct size valves & never got around to it. The missing valves & rockers/Balls/Nutz not seen in the pictures will be included & the heads will be disassembled completely & checked for cracks by the local NAPA store at no extra charge if you request it. You will only receive 4 Guide Plates NOT 5 guide plates as shown in the pictures. I have the original short block as well removed from a Grand Prix or is it Gran Prix (Mandela Effect like the VW Emblem) which is not included here that going by memory was drilled & tapped for 4-Bolt Mains/Center Caps but came from the factory with 2-Bolt Center Caps if you are interested I will list it as well Standard Bore Crank & Block with Rods & Pistons.
