S&S Retro Panhead Conversion Kit

Here’s a way to give your Shovelhead engine the nostalgic look of a Panhead and improve performance at the same time.

The Retro Conversion kit consists of a set of S&S P-Series cylinder heads with rocker cradles, S&S roller rocker arms, S&S hydraulic tappets, billet tappet guides, Quickee pushrods, pushrod cover clips and the required gaskets and hardware for assembly. Pan covers are not included to allow option of using any style desired. The S&S P-Series heads included with the S&S Retro Conversion kit are the same heads that come on the new S&S P-Series engines. These heads have a Shovel head bolt pattern that makes these heads compatible with any stock or aftermarket cylinder for 1966-’84 big twins. They are designed to accept stock or S&S o-ring style manifolds for Shovelhead and accept any exhaust system made to fit a shovel engine. Heads come complete with valves and .590” lift valve springs. The billet tappet guides, tappets and Quickee pushrods are set up to oil the top end through the pushrods, just like on Evo models. The Retro Conversion kit requires that a 1984-‘99 style cam be used to ensure correct valve timing. 1970-’77 stock engines will also require a 1978-87 style pinion gear to mate with the late style cam gear. 1966-’69 engines or other engines with generator style crankcases will require a special generator style cam with 1984-’99 style lobes (see section “Cams”). Three versons of conversion kits are available: with heads for stock bore cylinders, with heads for 3-5/8” big bore cylinders or with dual plug heads for 3-5/8” big bore cylinders.
