With my combo what cfm do I need? I was thinking between 240-250cfm

You should have 260-275 cfm if you really want to maximise those heads on a strong running 358. The 1.95" intake will make that a tough place to get to!

What makes more sense as far as mid range torque, 2.02 or 2.00. The heads I previously had on it were Vortec Bow tie large runner heads with roughly 215 to 220cc runners 202/160 valves and a 252/255 4/7 cam at 108(4 degrees advanced, but flat had no torque and required excessive gearing to remotely compete with the top 3 cars.

When you brought up the large bowtie vortecs before, I recommended that you call Mike Jones for a cam. Did you do that?

Yes. He recommended the cam I’ve posted but he said the head is too big.

The rules are wide open on the heads, you can 10:1 compression, but the front runners have almost stock CH350C heads?

I can tell you the CH350C’s (un-ported because of rules) were front runners and the guy was teched all the time, but that was a 2/5 mile dirt track. I’d have to look up the cam. It was a Mike Jones, I think in the 230’s,maybe 240, .500 lift, 106 or maybe 108.
If that works for you...

The way I'm gathering is both the C and H have similar characteristics, show the same flow info on the aamidwest(eq website), of course having different intake patterns might make them different. I really don't want to do much to them other than match up with a victor jr or super victor(with plenum work). best valve job possible, eliminate any flow restriction when the valve opens i.e. clean path off the valve seat. The large vortec port on the left, eq 350h on the right.
