I have a similar problem I bought a set of Headmans, had them coated inside and out. A beautiful job. They sit about 3/4's of a inch away from the lower A arm bushing on the drivers side. Counting coating I have about $450 tied up in these headers I'm not about to beat them up.
I bought a new trans cross member and have a 700R4 going in there. The cross member is slotted I think I can move the engine back another 1/4 to 3/8's inch. I think there is enough firewall clearance with the HEI to do that.
My concern with that is that maybe the heat will be enough to boil out the lube.
Any tips with similar situation would be appreciated. They do hang a little low going into the collector but I can live with that. I will be driving all pavement so just have to keep an eye out for surprise dips.
