Need some cam info: 355 with flat top pistons, gm heads and need to pull 16" vacumn at 1000 rpm's

Anybody have the same rules?
Not sure on size of valves yet, any info would be appreciated.

Will your rules allow bleed off lifters and do they say anything about valve lash?....Towman

Nothing about valve lash , only hydraulic lifters.
I was looking at the Rhoades lifters.
but not sure about best cam size.

I'd say anything in the .220-.230 duration.050 range should pull that as long as you keep the lobe sep around 112*-114*
