Hi guys,
yes, I know I'm asking too many questions at the moment and not fiddling for myself :-) But here's my next question:

I read somewhere that to set your valves on a 350 SBC you want to screw in the rockerarm nuts til you fell a resistance when turning the pudhrods, then a halfturn more. I did that, but it seems like I overdid a few, it ran OK, but used masses of gas. I guess none of the valves fully closed anymore.
Can that damage the lifters? I've corrected that condition now, but some lifters are depressable by hand (I can push the pushrods into them a bit) but others won't budge. Do I need new lifters?
As always: Thanks in advance!
