edelbrock heads

My heads were hand ported stage 3s by Hughes in Dec 2006. The peak flow numbers are 299 at .600 lift.2.08 ,1.6 valves. I run their older version of the AS 276/280 solid flat tappet cam . Car runs 10.0s over 131in the heat with the 410 cid motor and the car weighs 3093#s.
Stage 3 port work needs a big cam to take advantage of the cylinder head.
