I'm not sure which Devcon Your Useing But the Devcon I bought (metal Patch&Fillcompound)isn't worth the crap. Never had this on a Motor But Had it in my Van Where I had Did a Blending on some lumps for Pictures for my web site and Just from the few months that the head peices sat in my Van That Stuff started to Flake Off JUST From the Heat In the Van.SO My 2cents On Devcon Is Find Something Else.
Now Onto The Full epoxy Lump One Of the Better ways to do this Is to put some small dixie cups in the Port and fill it in around the cups. Once it's dry and hardend up. You can take the cups out and start your Port work from there.Now as for the Lumps all being the same. From Epoxy made wouldn't be much different then that Of PES bolt in lumps.They Need to be Reshaped If you do not plan on useing their intake & head gasket.Or you Must make a peice to bolt into your head. Again they can very a little.
Now To toot my own horn One Mit say. My Bolt in Lumps Are all Matched and Fully Preshaped. To the Point all You will have to do Is Remove the Boss drill the head to be able to bolt them into the head. AND The next step IF You want to get the Maximum FLOW from the lumps is to finish Epxoy Blending the to the back of the Port.ALSO to get the maximum CFMs out of the heads, Their a few others things that do need to be addressed Like The Valve Boss. To either round/tapper it off More Or Remove it all together. But Removeing it Is not a good Idea For a Daily Driver Because (Now Think about This) Once you remove the Valve guide boss from the Inside of the head, AND Trim the Tops for PC seals and the Bigger heavier valve spring,You Now have made the Upper half of the guide shorter. Which this Inturn Mades for a Unstable Valve For a Daily Driver Putting more wear on the Guide itself.
As soon as I get this New computor all straighened OuT and software reinstalled ?some new software as well. Because i stepped up to windows xp Pro.So some of my old software doesn't work. I will Get back On my web site Up dateing The Head & Lump port Photos Which Will show The Full installation of the Lumps and The Full Kit that I sell. Along with Some photos of the Engine Companys Intake Manifolds from our Friends In South Brazil. I have like 6 different intakes and a Valve cover & side covers from them I also have a New ALUM thermo Housing , a rockerarm stud griddle/guide So Please give me about a week to get all this Up.
Thank You }[oooooo]
God doesn't like ugly.
