Buckeye1647545503 Posted February 7, 2004 Report Share Posted February 7, 2004 I am geting ready to "home port" a set of heads to use till funds allow for better ones. So anyways I want to eliminate the smog pump bump next to the valve. I have discussed this with a friend who sugg useing a steel plug then porting it down with the rest but I was wondering if there was a epoxy to use to fill the hole instead. Something that can with stand the heat( and maybe spray). Also I AM doing myself so please don't tell me to take it to m&m or what not. I thank you for any help any help -Scott- Quote Link to comment Share on other sites More sharing options...
still2hi Posted February 7, 2004 Report Share Posted February 7, 2004 i dont think there is any type of epoxy that can hold the pressure and heat. i have seen steel plugs before, but have never used them or heard about them. ever think about getting a tape set and making some threads and screwing in a plug..

slow4now Posted February 7, 2004 Report Share Posted February 7, 2004 Weld it shut. I don't know of an epoxy that would work nor would I want to try it that way. #1 reason for broken cars = people not doing things right! smile.gif Quote Link to comment Share on other sites More sharing options...

ridenred27 Posted February 7, 2004 Report Share Posted February 7, 2004 pc-7 that is what larry morgan uses to fill and contour the ports. also you can buy a high nickel content arc stick and it will hold but you will have to preheat the weld area first. that is what you called me for Quote Link to comment Share on other sites More sharing options...

desperado Posted February 8, 2004 Report Share Posted February 8, 2004 Hmmm, that is alot of welding, as far as the rods. I have 20 lbs of it in the garage now. But cast has to be heated or it will crack from the welding heat. Another way to do what you are wanting to do is to braze a piece of metal in there. As far as the epoxy's. There are a few that guys use it drag motors in the exhaust tract. But not a street motor. Reason is that the heat cycling is alot greater, and that tends to crack the epoxy.
