I just pulled the heads apart on a 283 I've got, just to have a quick check of the bores, springs and lap the valves.
My buddy suggested machining the guides to take modern oil seals, but I just want to throw this together and see if it runs okay, then do a full overhaul some day in the future a funds allow. He suggested I use the stock little O rings that slip on the valves, before the collets/keepers etc. How the HELL are you supposed to get these together???
And why are they square section, not round, like normal O rings? There is no bevel or lead on the retainer to help it slip over.
As soon as I compress the spring and all down over the valve the O ring just pushes out of place.
I even tried a simple little spring compressor that allows me to wiggle and rotate the spring assembly as I push it over the O ring.
What on earth am I missing here? I can see with a flash-light that half the O rings have pushed out of place.
