Headers for my 318

My motor has an old direct connection .455 lift 272 duration cam and lifter kit. I put it in my dads stick shift shorty van back in the eighties. It still had the two barrel intake so needless to say it did not run too good but I was a kid then and did not know any better. The motor is now in my beater '70 dart with a performer 318/360, TQ off a '73 440 and an F-body O/D trans. The cam might be a bit big for the stock low compression '81 bottom end but runs real good. I did port the hell out of the heads and port match the intake. If I get around to it I will put some zero decked flat tops in it. Too many projects.
