what is the trick for installing new head orings the inners I tried heating them up with a heat gun and stretching them some but no luck I double checked the p/n and I have the right ones. They are too small and wont stay in place.

You could try soaking them in Anti-freeze for a few minutes, see if they are easier to form and stay in place that way.

Are the orings at least close to being seated or are they 1/4" away.
I use a bit of grease on the ring at 4 sides to help keep the ring in place while I align the head
Rot.

yes they are small about 1\8 too small, the outers fit right in so Im wondering why the inners are so small

sure they didn't give you a 700 kit or something? usually they fit pretty good, a dab of grease is all i use as well

part number 5411675 is what I have that is for 800 both of the the new orings are the same size but seem small

Just pull on them slightly to stretch them a little bigger than the groove. Then hurry up and set the heads in place before the O ring shrinks back.

how cold is it where your working? hot water and a warm work area sould be the very most you need !

Bingo, that's the correct way to size them.
