318 la head vs magnum head swap help

I also plan to do a 100 shot of the bottle on my Magnum motor btw.

i hope to do the same, i'm sure it would take it fine. i watched my buddy spray a 150 shot to a bonestock 8:1 350 chevy for a couple seasons, with nothing more than timing retarded, and colder plugs,. my father ended up with the motor, its still runing today and still holds 50lbs oil press. goin down the road. that thing was a dog off the bottle LOL i don't remember what it ran on motor but it only ran 8.20's 1/8th mi. on the 150 shot Lmao so if a chevy can handle it, i know a mopar motor can easily.
