I would go VVL. Allows to rev higher with more availability of parts. GTiR is old tech.

Yes, a lightly worked over VE head should flow over 300cfm pretty easily.

The Pulsar head is the best flowing DET head but I believe the VVL head flows better. I switched from a stock Pulsar head to a stock VVL head and I noticed a difference.
