Need some help with VE factor

[tminer]

Stock stroke, .020 over bore, 218/218 Comp Roller (3313 lobe) 113* & +2, GN1 heads with 1.60 rockers and mild hand porting, 70mm TB/UP, ported intake, Poston headers, 3" THDP. Compression ratio is undetermined but shooting for 9:1, maybe a little less.

Looking for a reasonable VE factor to use in various calculations. Also, will it change significantly with RPM?

Thanks,
Tom
