If you use the "hot" settings when the engine is cold it will end up being too loose when you check it at operating temp. It will probably need to be about 2 thou tighter when done cold although loose is ok, too tight will hang a valve.

aaaahhhhh by "hot i thought uz meant best for power[:p] when I get home ill be re3checking anyway ill just muck around with it till its good
does 12thou exhaust & 8 thou inlet sound normal? I cant get in contact with my engine guy but what settings do u guys reckn they normaly give u

well re-checked my clearances were pretty close no major adjustments just minor, still sounds the same could it just be the beefy cam? sounds like a typewriter, what do you guys reckon about just messin with it till it sounds right??

Who reground the cam and are the followers new or refaced? What is the profile? When you check the clearance are you working on a slight drag or a go-no go proceedure?

On a typical solid lifter V8 you can vary the clearance by about 6 thou looser and 4 thou tighter. On a ohc motor they haven't got the same clearance ramps to play with. In reality you would hardly notice any change in the valve clearance from a performance perspective unless the combination was perfectly optimised. You probably have about +-2 thou to play with which will be attributed to "your" feel with the gauges. Some cam profiles can be a little noisier, Comp cam extreme series hydaulics are very touchy to preload and can be tappy. Cams with aggresive profiles can be noisier because they tend to compromise the clearance ramps for higher lift rates.
