Stock Magnum heads vs Aluminum edelbrock heads
It sounds like you’re trying to stay in a budget…if so…Then I would grab a set of the bare Jegs, Summit or Speedmaster iron heads and then have Magnesium Valve guides installed… get ahold of
@PROSTOCKTOM for a set of SI factory size valves… a set of PAC 1286-16 springs along with the recommended retainers, do a pocket port and flash clean up… and you can still use the factory rockers and pushrods … then call Ken at Oregon Cams and tell him your plans… get your cam and put it together and go have fun.
As I said in the beginning…we’re limited on Magnum heads and unless you just want to spend the dough on Edelbrocks and budget is not an issue… then go that route as you can always use them on a bigger motor in case plans change later down the road… but you will still need to have the Eddys checked out for tolerances and any casting debris.
Hope this helps!!!
I’m sure they’re others that will chime in hopefully!!!
