OK so here's the same port with the pushrod pinch opened up
from .780" to .965".....typical of a decent port match.

.100"_____62.1
.200"____125.3
.300"____181.5
.400"____220.6
.500"____235.3
.550"____239.0*
Backs up over .550"

* slight turbulance



so are these numbers a net gain..after mods.?.
or a net loss...?
