$195 + shipping Pair of recently rebuilt 14101083 casting # 64cc 1.94/1.5 iron heads (1987-1992 5.7 camaro/firebird TPI heads). The valve guides were bored .015" oversize and new oversize stem valves fitted, and full valve job done, about 10k miles ago. The valve stem premium viton seals are still nice and fresh. Ready to run. The valve springs are stock and should be replaced if you plan on running a cam larger than ~ .450" lift. These are a great head to replace your high mileage worn out 083 heads or replace your TBI heads.









Each 083 head, in a box, weighs 54 lbs and measures 23x9x7, for shipping reference.

Those heads just sold but I have one more pair of 083 heads w/ similar very low mileage, under 10k miles, that also have a fresh 3 angle valve job, all new valves and resized guides, and additionally have new aftermarket valve springs set up for a mild hyd roller cam, and have been pocket ported. All the valve installed heights were shimmed to get consistent, correct spring pressures @ 1.75" installed height, and I used 16 regular non-rotator retainers. These springs are good for .550" lift but I would verify guide to retainer clearance if you are planning on running a cam at or above .485"+ lift. I am pulling them off a .450/.460" roller cammed .040 over TPI setup that I was running in a truck. I would sell these 083 heads at the same price $195+ shipping

Shipping is $104 for both heads to your zip

This is what they are coming off (1988 K1500 that has a frame that is succumbing to rust), if you want the heads I will pull them immediately and send you pictures before shipping them.





Here are the heads from when this engine was going together a few years ago
