Sorry for changing the subject, but I have a 2nd gen teg and just did a full rebuild from the lower bearings up. I have it running but there is a knock in the head, lifter or valve in the exhaust side maybe cylinders 1 or 2. I had the same head running in it befor this and no issue. Any ideas, some of the lifters wouldn't even touch the cam untill the lobe came around to hit the lifter. Do I dare try to adjust the lifter settings? I have to much time into this already and dont want to start over untill absolutely necessary. any ideas or knowledge?
