valve retainer to seal clearance-thinner seals?
 

so, without any seals i have .750 of valve travel. with OE umbrellas i have .580 of travel. i would like to get 550 lift. is there an umbrella seal with a thinner roof to get more clearance without machining guides? 3/8ths stems. oval port.

i've seen some for chrysler 440's that are thin umbralla's.

Guide cutting tool isnt that expensive . https://www.youtube.com/watch?v=7aTXiay8M9k just take your time .GOOD LUCK!!!

or just run it without seals,you wont be the first guy to do it.

ordered a set of comp cams seals. should be in today. will report back with diff in thickness to OEM. i am sure quite a few of us want to go from 480 to 530-560 or so lift and it would be nice to be ok without needing machine work...

let me know,,I can dig some up at the shop and send them to you.

Come on Mike.. why would you post crap like that? Someone on here might think its ok and actually do it. Your not letting Alex get to you.. are you?

not crap.im dead serious.i have seen guys do it.alex who?i took a sbc apart one time that had 150 thousand hard miles on it.no signs of valve seals but it still ran good,just a little tired.

usually only on the exhaust,,and when the guides are extra high or the springs have the damper in them.also,the valves will get the little o-ring that goes in the second groove of the valve stem.

When I raced circle track in the 1990's , It was pretty common not to run ANY seals . Different schools of thought , trends , ect.
