looks good...and as for the valve cover...
get the aircraft remover and let it soak for awhile,,then wirebrush it..clean it up nice and go to autozone,get the HIGH HEAT ceramic shit--its like $5.49 a can
get the primer and whatever color youd like,,thats how i did mine and it came out really nice..
the regular paint works but after awhile it gets likebrittle or something and scratches/cracks real easy(thats how mine was done the first time)
