I have started to rebuild my 351C 4V and i have run into a problem.
The thing is that i accidently damaged one of the seals and while looking around for a new pack of seals i read that i have to machine the valve guides with a special tool... Now if i managed to get 10 of the seals in there i assume that this has already been done or what ?
There is no evidence to machining though ?
As always there´s only lousy information on the matter online so i need an experts knowledege here.
What should i do ? Help !
