Well the Vic Jr's won't give you the lower end that you're thinking of.....but that's what I'm saying....a Cobra is a very light car...which is forgiving in the low-end department along with carb selection, etc.

You would probably be fine with the Vic Jr's, but I think I would kinda lean towards the smaller ports of the Performer RPM heads.

For the RPM range that you're looking at and to have a good shove back into the seat, I'd shoot for torque. The smaller ports of the RPM heads would give you that....whereas the Vic Jr. heads would need more revs to keep the air velocity momentum up.

With the RPM heads, the roller cam that I spec'd, and the RPM Air Gap, I think you'd have a lot of low to mid range torque/power.

The Probe pistons will work well with the Scat components. If those SRP pistons were 11cc dish pistons, then I think the compression ratio would be lower than what would be optimum for your application.
