Oh FFS.

OK, for the purposes of usefulness, what could you do with a -1 or B-1 offset rocker and say a 6.0 to 6.2 OAL valve of 2.30 or so diameter to fit within a 4.8 BS block?

The NASCAR guys are running valves that long in 358's with 4.1 bores and making 900+ HP that lives for 500-600 miles, so why not a BB? S/F.....Ken M
