1967-68 Corvette Camaro Nova Impala 3917291 Double Hump Bare Heads/Pr. 1.94 1.50

This is for a Pair of Bare 3917291 Heads, (GM Part Number 3917291, GM Group Number 0.268), Dated A 2 8 and A 6 8, (January 2nd and 8th of 1968). These heads have been hot tanked, shot blasted, tumbled, cleaned, inspected and magnafluxed and are guaranteed machinable and guaranteed to be free of cracks. These particular heads have new Engine Pro screw-in studs and guide plates and the factory pushrod guides in the head have been drilled out for pushrod clearance. They are currently bare and are for 1.94"/1.50" valves, although your favorite machine shop, (hopefully that would be our shop), could open them up for 2.02"/1.60" valves if desired. These are the 1968 and older style heads that do not have the accessory bolt holes in the end of the head. If these are not dated correctly for your application, we have over 100 more in stock. You can have your choice of dates while they is still available. Please call for specific info. They can be used for a dated restoration project, Corvette, Camaro, Chevelle, Nova Chevy II, Impala, Bel Air, etc. or for a hot rod, street rod, retro rod, race car or many other applications. "Keep Your GM Car All GM!" This is what you need for your Bloomington Gold, NCRS Top Flight Restoration or Survivor Car! This item can be picked up at our Corvette Parts and Service Center, Tracy Performance, 29069 Calahan Road, Roseville, Michigan 48066-1805, (just Northeast of Detroit), to save shipping costs.
