I wasn't considering custom pushrods? benefit vs cost? I didn't realize if I had the heads milled and used a partial MLS gasket I'd need shorter pushrods. Makes sense I guess, so then the question is throw a stock L67 together with a na upper? Or spend a little money on milled heads and 2 layer MLS to gain some compression? even more compression with a NA bottom end obviously.
Main reason for the MLS gaskets is id like to hit it with a bottle eventually. (speaking of nitrous stay stock bottom end with NA upper because it would be easy to duplicate if I chunk it on the bottle?)
Last anyone know if milled heads and 2 layers from the MLS gaskets would cause clearance issues?
