Anyone have any pictures on what needs to be clearanced on the rocker stands? My engine is starting to lope and it is using quite a bit of antifreeze, so I think I have put it off as long as possible...

 

If this has been going on for awhile, you might look down on a pretty cheesy piston when you pull the head.

Here's a recent thread on head studs with pictures.

Jeez, I hope I didn't hurt a piston. I plan on lapping the valves to check their contact area. If I have hurt a piston then I will just yank the engine and start saving for parts.

 

Check in on extream studs . Com, word on the street is they are holding up very well in tractors, and a few street trucks. They are supposed to be as strong as 625's. I have no experience with them yet, just what I've read.
