Also if you don't have intake yet I'd go rpm airgap. I plan on switching sometime down the road. Theres a shoot out between the airgap and the M1 single plain. Both make similar top end but airgap makes 40 lbs-ft at one point and 20 lbs-ft average down low.
Especially will come in handy were your going 5.2.

Also if you decide to go EQ or edlebrock heads you'll just pick up 30-50 more hp plus opens cam choice since you can go more lift.

I already bought from Ebay the knock off Assault dualplane air gap intake...
No A/C, No P/S so it should work
It's a bone stock 5.2, I'm thinking the stock springs will run the cam, I know it's best to replace but funds are limited like a fat lady squeezing a poot on a church bench, I expect the bashers to chime in but it's not their wallet..
273, Any chance you have a video of your car running? What exhaust are you running?
Always wanted a Thumping Mopar "sounds so good"

If the heads are stock no reason to by them, Just cam and converter for the Mag...

Keep in mind this is a V8 swap from 170 Slant six, so either way I go the car will be faster. ATM it sit's waiting on an eng. I'm already $$$$ way over then planned
I have an extra set Hooker fenderwell headers for sale already posted..

My original plan was 1979 318LA, flat tops, "1990 714 hogged out heads needs 3 angel valve job", "0.28 head gaskets also fits Mag" with 256/268 .447/.455 flat tappet cam, Offy Port O Sonic intake, 500 cfm Holley 2 bbl.. and still may use for mockup

The Magnum 5.2 is in my first gen Dakota parts truck
