Hi,
at a swapmeet a few weeks ago i purchased a set of aluminum valvecovers engraved with "JC PERF".
does anyone know the origins of these parts.
They seem to be for a 25/30hp engine, because the rockershaft studs don't line up with the mounting holes in the covers. The holes are drilled 3-4mm higher than the studs in a late model head.

JC Performance used to manufacture some nice cylinder heads back in the 70's or 80's.
