Crossover Tube and Valve Spring Pressure Questions

if you really want to turn the R's then i'd say you should be looking in the direction of a solid lifter or roller setup. that's not to say hydros won't or can't work, but it's not ideal.

is there any particular reason why you want to have that much ceiling in the motor?
Well the trans went out on the way home from a buddies house last Sunday and at the same time the current engine started huffing a considerable amount of oil out of the exhaust and breathers. then my intake bolts pulled the threads out of the heads. all In one day.

so Im building the engine I have in order to get the car up and running again which is why it's a 318 and not a stroker 360 or 340 or something like that. and to get the power I want out of it and to have a little fun too, it'll need to spin a little higher. (I also really love a screaming small block)
