i was wondering, since i will have my intake and stuff off for a cam swap, my lifter valley is pretty cruddy. could i just spray like degreaser or whatever in there and let it all fall down out of the bottom of my block? or would that be dangerous to bearings and such?

 

Wont make a difference. Best thing to do is just wipe/suck anything thats there out. No need to spray anything inside. Dont fix what aint broke
