Indy/RHS Heads

.700 lifts can be a reality but the thing here is at what cost is this going to happen. The thing with running a taller valve is the retainer to rocker clearence, or the rocker to VC clearence at full lift. Taller studs like what I'm going to be using will help this out some, so it will be like a high lift cam in a sbc. The main thing here too is the spring diameter, I'm going to see if I can get a good 1.43-1.47 spring, this will allow for more rocker to retainer clearence.
