I went ahead and purchased new engnbldr EPN valve guides $58/set 16. At the same time I inquired about other parts EPN supply and they let me know that they still had a box of 80 2.19 intake valves std length for $7.50 ea. So I thought, what the hell, and purchased 8. No sets of exhaust valves were availible although they may eventually go through their extras bin and offer them on ebay. EPN claims the valves come from the same mfg and are the same valve offered by a big brand name.
They even go so far as to have 11800EPN lasered on the valve stem. I plan on weighing the valve for comparison to other published weights. I will probably puchase a "real" 11800 valve the next time I order from the big parts house for comparison. Is there anything visually to look for as far as quality goes? What determines quality other than brand, reputation and experience? The new valves roll around the granite counter top as smooth as a Swiss watch. The stock valve starts to surge when it slows down. I know, not a very scientific measurment for valve concentricity.
Does anyone know who actually manufactures SS valves? Eaton? Regardless of the country of origin, is a SS single groove valve likely going to be more reliable then the stocker?
I have not come accross any negative reviews of EPN other than"you play your cards, you take your chances" kind of comments from engine builders that can not afford to ruin their reputation trying to save 1% on an engine build.
I would not have considered these valves but the reviews of the guides and customer service from Ted
at EPN have been very good.
