Guys' I'm checking all these other points you have brought up. The springs do appear to be stock. The engine runs normal right up until one breaks. There is no indication that something is going to happen. No popping, backfireing or sluggish operation. The pushrods aren't bending. The valve train is real wet from oil. I've been told to remove guide seals. What do you think? OIlrag I'll take you up on your generous offer. I have the side cover off and am going to rebuild the lifters also. As much as I hate to, I think I'll end up pulling the head. Also OIlrag the eng is a 51 235 w/powerglide from a car that is now coupled to a man 3 speed. Block # 3692703, head 3835499, manifold 3835590.
Glenn,
