anyone who has used beehive springs on unmodified vortec heads? iv been looking for valve stem seals, preferbly viton. i read an article where they used umbrella type seals for increased valve clearance, though i cant seem to find it now. i have a sealed power part # ST2015 but i can tfind it anywhere. if anyone knows where i can find these that owuld be great.i do not want to modify the guides either so only info onparts that fit the factory heads please

 

would i have better luck in a different forum?

 

Dunno man, I would try the motor swap forum?
