How would you rebuild this 318?

Do you remember what the lift is for your cam? The duration at 0.050 looks good to me

.468. 224/[email protected], SFT. Low compression ‘73 340, stock bore, 273 rockers, stock heads/manifolds, LD340 intake.
I would like to optimize the iron heads and use a different piston and head gasket.
It’s my cruiser so I don’t want to tear it down yet.
