Thanks everybody for your input, I really appreciate it.
Since the SM heads have the bigger runners, I will install those on the 463 with a solid roller Paul Kippens sold me sometime back. I have new Howards Cams 98541 springs and new Comp Cams retainers and locks to go with it.
The KRE D-ports along with the Dougs headers I'm running will go to the future 428 for my 81 T/A.
