Hello
I took a set of cylinder head to a local machine shop to have the valve guides replaced, valves resurfaced with new seals
When I picked them up I looked threw the exhaust and intake ports to see in the guides were replaced and notice in the exhaust port that the stem on the lower part of the exhaust guide was cracked and will this effect the cylinder head in time ?
All of them came back with a crack at the lower tip and One came with a piece missing.
The person at the machine shop told me that this happens with a new guide is press in..
I would like to know in these heads are toast and I should be looking for another set ?
Thanks for any advice Arthur
