" only have the ability to run mid-high 13s at best." That a good point !! the ported heads allow the flow and velocity for the 12s!! Cam , induction, fuel,
suspension, blah...blah... wont put you in the 12s with AFRs and a blower.... If it isnt right or at least close to being right!! Cool??

Plus a lot more... but to say "you will" is not the same as saying "you can" cool?? There is no way to know your engine and
suspension and driving skills... see what I mean?? BUT.. the Heads will allow power for the 12s and faster with power adders!!
Just me.................................
