Anyone know how deep you can cut the spring pockets on a RHS LA head? I am tring to get to a 1.8" installed height with beehive springs from Hughes. Dont want to hit the water jacket.

Get taller valves.

You can get some additional installed height with +.050" locks and/or retainers. Comp Cams has a few versions for beehives, but you need to find what fits your particular springs and valve stems.
