he car came to me with dual SK sidedrafts (Weber rip-offs) and the head had s=
ome interesting stuff done to it.The intake area on the head was carved out t=
o raise the angle of the SK's and the combustion chambers were recessed with=
a flat mill to fit pop up pistons to gain compression without much head mil=
ling. I know others run pop-up pistons. Has anyone else done this?
