They're shit - the rear cylinder head porting is all to fuck to fit that pipe routing. If you go racing, you have to use two front cylider heads, so both exhaust pipes come out of the front of the heads, not one front, one rear.

maybe so, but after dry/wet sanding with 400/600/800/1000/1200/1500/2000/3000 grit and 2 polishes with autosol, they are now shiny shiny! (:
