Scorpion Roller Rockers
Anyone ever disassemble Scorpion roller rockers? I'm trying to loosen the allen bolts that go thru the pedestal into the head on a Roush crate engine. Even with MAPP gas heat at the head area under the pedestal none of them budge. I sent an e mail off to Roush considering these are only supposed to be fastened to 20 ft. lbs. Any help appreciated.

valve closed? or open? if there is spring tension it may seem very tight. |

Thanks. Finally got things loose after learning that the nut needs to be loosened, not the allen bolt.

Leaking head gasket. Heads also need cleaning and intake valve stems look like oil is getting sucked past seals. Haven't disassembled valves yet to check guide wear. |
