Thread: 390 Oil...where is it going?

Tweet

on iron guides i use a 502 spiral cut guide. i like the added oil on the stems and use them. much like a remflow.. snake skin stem valves will add oil to stem/guilde free up hp .when they are just a wee bit loose i knurled them in lower dollar jobs . like louey said long as the guild s are not beat out it works good .i feel that a straight wall iron guilde could use abit more oil for hp use. i try to used manganese bronze in most head builds as the manganese is hi zinc and helps lube the valve stem. i can see a machine shop selling you guides as i am sure they make more money putting in guildes . i know i do.. some guys look down on some things thinking there is only one way to do a job .just like knurled pistons is good fix and holds more oil on the skirt .many guys just do not have the tools to do some jobs so they may bad mouth a job were there way may be faster or they make more money or both
