I know many Use the Devcon That is one reason why I bought it to try it.Well it did come from auto Zone LOL so who knows. This Could have just been a Bad Tube I use a lot of The A&B epoxy from moroso and JB Weld Industro Cold weld compound And Just started to play with One other Brand Which at this time seems Much Stronger and Lighter.
I know that leaving the Guide itself will Help the Valve. BUT Some Do cut the whole thing Out and I was Just Stating THAT It is not a good thing to have it all REMOVED. I have a Head Here Right Now That Was Done Many Years ago By Crane and It has No Valve Boss Guide Or Guide showing in the Head. NameLy the Exhaust Side. But anyway.When I get half a chance Jim I need to give you a ring. }[oooooo]
