I've got an E303 in a DSS Pro 306.
Although I went from a B303 to a Comp cams XE274HR to the E303
Comp Cam specs
.555/.565 lift
224/232 duration at 112 Degrees of lobe separation.
But, after I found out that the shop that did work on the car timed me at 16 degrees BTDC it sound a lot better.
Little Lobe, not as much as the Comp cams.
