Sounds like you have a nice combo there really... and I don't want to sound like I'm bashing cuz I'm not, just being realistic... Flat tops in a 350 will give you a 10.3 Compression ratio, with a 64cc head. the Vortecs flow about 220 CFM which is worth about 450 HP Max...
Take a look at this article, it is almost identical to your Combo, they also test a Holley versus a Demon...
By the way, the Shavings was a problem a long time ago, and they did clean up their act. the Demon I had was Awesome, hardly had to do any tweaking to get it running really clean... I just sold a Holley 750 DP that I couldn't get to run cleanly with My Current Combo and I ended up Buying a Pro-systems 850 CFM...
