Re: should i run the 1406 eddy or he 670 avenger

Re: performer rpm/rpm air gap/victor jr will they fit under stock hood?

You were correct. I just had to wait for the lifter to bleed off after tightening and idle would return to normal. I don't think the ticking has anything to do with the lifters.
