The billet tappet blocks are made from 7075-T651 with a tensile strength of 83,000 psi which is almost triple the amount of cast tappet blocks. Fits Panheads 1953 thru 1964 and Shovelhead from 1965 thru 1984. Do not use the early tapered 1/4"-24 screws on these blocks unless you provide a counter sunk for that style screws. Note: These blocks are designed to accommodate a gross valve lift of .550" at the valves. This is about .350" at the tappets, leaving a clearance of .035" roller to block free play. If used with higher lift cams tappets must be modified. Use with standard pushrods or equivalent to standard pushrods. 2120 JIMS BILLET BIG AXLE TAPPET BLOCK KITS TAPPET BLOCKS (Ȧ*ȡ1ȝ (Site 491)
