Building a 360 it's .030 over, has hyper 4 relief flat pistons, purpleshaft .484 cam. Thinking about trying magnum heads. What all do I need and who has used them and did you like them

need to have oil thru lifters and hollow push rods

and the intake bolt pattern needs to be figured out..carb intake with mag bolt pattern or redrill or the EQ heads(mag with LA intake bolt pattern)

is it a roller cam block? or older LA block?

if roller block,stock roller lifters and mag push rods,IIRC will work..

if it flat it will have to be measured for correct PR length

check the valve reliefs to make sure they are big enuff for the 1.92 mag valve( but most likly are gonna be down the hole far enuff)

you will need the rest of the bolt ons for the 484 cam..carb/intake/headers/HS-TC/gears

heads should bump the CR up a tad so thats a +

you'll need decent springs, too...
