If you never have to sell the car, then no smog worries. You lucky dogs in Humbolt.
Basically you need to look at the entire function of the motor and what you want to achieve within your budget.
In other words, your cam choice, needs to match your intended use and it needs to be compatible with your intake, exhaust, carbs/ FI. If you choose a cam that will work with carbs/EFI, you will need to change out the pistons, since CIS pistons don't have the clearance needed by say an S cam.
Anything much over 9.5 to 1 CR will require twin plugs. $$$$
A dream motor IMO would be 92 to 93mm P&Cs, S cams, twin plugs and around 10.5-1 CR with Webers or MFI.
Good luck.
