take a deep breath and think how you want to drive it and how much
Piston and head choice go together and you need to change both then a cam that goes with your pistons and head
Measure twice cut once
you have an intake and carb- no reason to change now
if pistons and heads are not both in the budget stick the shortest lunati voodo in your short block and drive it for awhile
that MP cam is great with more compression, converter, headers, gears but not for U
but I would not want to drive it around much with street gears except for road racy type use
as far as heads go EQ iron or Edelbrock off E bay minimum
figure the cc's and use the dished or FT KB pistons to get the compression streetable
with that combination you can run the MP cam and see what else you have to change
changing everything at once and finding out you are wrong is no fun and expensive
you can always have the MP cam reground till you get close to what you need
I'd sent it to Jim at Racer Brown and ask him
It's not going to idle the way you want it
