ls1 flow numbers
LS1 heads usually go high 220s/low 230s on the intake and high 170s/low 180s on the exhaust. Mine ported go 272+ on the intake and 220+ on the exhaust and there are some from other sponsors that go more than that on the bench.

You will never see these numbers in a race.
.25 and .50, yeah right on a pocket bike maybe.
