If your not doing anything to the short block and your looking to run something bigger then your stock 067 cam that will add some nice power And not detract from drivability then you must with a 400 cid motor get the compression up to 9.2 by hook or crook.
That’s why I posted go for rebuilding your 62 heads.
A needed valve job will add 1.2 CCs to the chamber volume and the use of a thicker then .039” head gasket should get you right there.
