Question?

I need the instant torque a Roots Blower offers.
If I build a blown motor with the newer SCJ heads, does holding the .600 valve lift flow rule still pertain for the head's flow dynamics?
Or is the fact that it's forced fed, blow past the head's sweet spot at .600 (as in a N.A. application) make it a moot point?
Can I run a larger lift camshaft with these heads and see a benefit.
If so in "general" what areas do I need to address with these heads with a blown setup?
Shooting for 700-800hp.

Thanks

I've used .720" lift....no ill effects that I could see.
