Can I get away with stock 318 exhaust manifolds on Magnum crate engine?

I just struck a deal with another FABO member for a nice lightly used Magnum 300 crate engine that will replace my old 318.

Until I can wrangle up some more cash, I am hoping to run my stock 318 manifolds.

What do you think? will I be able o get away with these for a while? Will they really strangle the engine?

Thanks for any opinions!

Depending on the year and type of your 318 manifolds, they may not cover the larger exhaust ports on the 360 engine.
