valve guides and seals

[72maverick]

Hey guys,

Ordered some valve seals a while back (viton .530 teal) and was wondering how hard should it be to get those things on there?

I had luck with a few but two of them are giving me hell. Think maybe an oversized guide was installed at some point?

Thanks

I believe install of those requires some machining.
I had mine done long time ago, but sorry I don't remember any of the specifics.

Well it said press fit. All but 2 went on fne which I find odd. I measure the guides and the two are slightly larger. Is that signs of previous work?
