Lee,
Sorry to hear about this setback. I know when Greg VanDeventer was working on my heads there were a lot of things to consider and even with trying to get the right valve guide seals I went through some gyrations with that. To further complicate it with aftermarket camshaft grinds he worked very closely with Aaron Scott since my cams were from SGC and then we went back and forth with Jerry and Kurt about the seals till we got the right ones. I don't remember all the technical details, but these LT5s really do require some Specialists in some areas; GVD reallys knows his stuff with these heads and can surely fix the issues if needed. I hope it all works out for you. Best wishes.
Craig
