Good question. I'm not sure on either of these. The RHS are on a 416 (semi-budget) bracket motor and the reason we chose those was to keep the initial build cost for the owner as low as possible and still get his heap to the target of mid-10's. I think I'm gonna grab another pair of RHS and let the guy that owns the bench have at it...
The EQ's we'll develop on a try-something-and-see-what-we-get mode. The more positive results we get, the more we'll keep poking around.
I'm a knucklehead, compared to alot of guys doing this head stuff and REALLY new to the small block stuff so I am in serious LEARN mode. Thankful to have a good guy with me on this!
