Ok heres the combo:
406 small block
10:5 cr
280H comp magnum
roller tip rockers
demon carb
weind dual plane intake
hooker header
2 chamber flowmaster
stock heads 194 * for now open to sugestions on what to run

what kind of power do you think i'll make the way it sits? and after a head swap to a nice free flowing set of heads? Thanks

That is about a 375 HP combo. Bolting on heads will add another 50 -100 depedning on which head. Are you sure you have a 10.5-1 cr?

Then you are right in there for a set of heads like the Performer RPM. :D
