SOMEONE PLEASE HELP
1. The installed height is 1.8", IIRC.
2. Yes, but they are too weak for anything except a stock cam. Something like 80# on the seat.
The cheap method is to run a "Z28" or "Z28 +.100" high lift valve spring with the inner damper removed. "Ghetto grind" the retainer to gain retainer to seal clearance.
Comp Cams #26915 and #26918 beehive springs are direct replacements for the Vortec spring- no machining. #26918 springs offer more lift capability and pressure. Use Comp Cams steel Retainer, #787. +0.050" locks can be used to gain some extra clearance; make up the spring installed height by using shims under the spring.
