Streetmaster to Airgap

Many heads can support 500 hp.
I've taken a 273 head, stuck 1.88 in it and opened it up to near 230cfm.. the low lift number were crap like stock 360 smogers .
Theres no secret, just power left on the table for the money/time spent.

So I'll ask you again since you're struggling with a clear answer. Can a 302 head make the power to push a 3400 brick down the 1/4 in the 11's?
