I have a set of aluminum stage2 #31 heads with 2.08" intake valves & 1.65" exhaust valves , they come complete with springs , retainers , valve covers , T&D roller rockers , lifters and pushrods plus a unmodified Buick Motor Sports off center carb intake -everything in great shape, there was a minor repair under one of the valve seats in one head which was professionally rewelded and new valve seat installed. Looking for $1500. for everything, only selling cause i dont believe i ll ever have the opportunity to build a full race stage2 motor. for any further info call- Matt anytime 347 680 8642-partial trades considered. thanks. also have a pair of exhaust header flanges and beginnings of pipes to build your own headers and maybe a set of header spacers go with the package.
