JIMS, machined aluminium tappet blocks 53-84. Polished

Polished forged aluminium. With optimised rocker box angles for a perfect seal. Machined to accept old cork gaskets or modern style double seals. Compatible with camshafts up to 0.550" lift. The tappet guides can easily be modified for higher lift camshafts. Improved replacement for rear 18602-80A and front 18603-80A.
Note: On 53-E76 engine cases you will need a threaded tappet block conversion kit for old style cases (502990 with Allen head or 513555 with acorn head), with flat style tappet blocks that will fit these modern style (flat) tappets.
