It's a 69 xhead. I have 3/8 size valves.... was looking for the valve guide size to order the correct valve stem seal... Example when I'm looking at valve stem seals they offer .500 or .530.....
Hi, kinda figured that.
The guides coulda been machined for either seal, prob. but not nec the .500, but unknown.
Take both, return what you don't use.
