Once i take the cams out,replace the head gasket(80 gs 1000L),then reinstall the head,cams,set the timing,etc then i turn the exhast cam to one of the lobes pointing straight up and check all the valve clearance on tha side,then rotate the intake cam and check all the clearances on that side? And if any are wrong then i do the shim thing correct? if some are say 4 and some 5 and some 3,but the acceptable range is 3-5 is it ok to leave them some different than the others? I am not sure my question makes sense.Sorry if it doesnt.I want to know...if i get lucky and all the clearances somehow are within whatever range the clymer book says then i dont have to do anything right,and if i do, do you do it the way i described.?
