I have an excellent set of used drop in style hydraulic roller lifters for a smallblock Chevy. These have the link bar so you can convert your old block to hydraulic roller with no machine work, etc. These are nearly $400 new, $200 will take these, ready to use. I also have an NOS 1971 LS-6 cylinder head. Casting number 188. This head is brand new and never used. It appears to have been a display head at one time as it is clear coated. This head is the same as the replacement 990 head. If you have a cracked one or damaged this head is untouched. $250 takes it. If interested please call me at 313-632-9100. Thanks, Rich
