JPS Aircooled’s Cylinder Heads are billet aluminum CNC machined replacements, not castings, manufactured according to the factory drawings, with a lot of improvements over old cast heads that are now more than 50 years old, worn out, and tired.
Don’t waste your time on reworking used heads. These 100% new “Sport Plus” CNC billet heads have ports that have been extensively flow bench tested with a lot of improvements and outperform any stock and most modified heads by far. No porting, polishing, or special modifications are required with these heads – they just work, right out of the box. They flow an amazing 195 CFM max with a stock Solex manifold (blended to match intake port on head) and 202 CFM with the optional JPS Aircooled Billet 48 IDA intake manifold.
JPS Sport Plus heads are designed and configured for use exclusively with CRE (Claus Ruppman Engineeirng) LN Engineering 93mm or 94mm Nickies Cylinders and JPS Custom 8mm head studs. Heads have 69.5cc chambers and are sold complete with 8mm stem diameter 42mm intake and 35mm exhaust valves, manganese valve guides, hardened seats, titanium valve spring retainers, and performance dual valve springs. Heads feature a black anodized exterior finish.
Don’t accept inferior components – JPS Aircooled products are precision made in Switzerland.
