my clinder head is getting a total overall and i ordered a complete set of valve guides, the problem is the old ones that were taken out were 13.02mm and the new ones are 13.07mm. anyway the clinder head was warmed upto to the correct temp and the guides were placed in liquid nitrogen, when the engine builder went to insert the guides they were way to big to go into the head does any one know the external diameter of a new guide? phoned the supplier up who supplied them and said it was very unusual and they have never had a problem like this before, any ideas anyone?

must be the same bacth pal, but mine were bought approx 3 years ago,

i think that there are some guides that are very similar in size poss for another car , that someone is selling as cosworth items

My mate bought some from e-bay and they were crap the valve stem oil seals wouldn't fit so he had to pay to have them removed and bought some from Woodford instead.
I got mine from there es well and they were fine
