X Heads on A 318

Hey All
I have an old school 318 That I plan on putting in my Dart to run while I get up the parts and$$$$$ to build my 70 340 nows heres the question when I say old school I mean old school... stock pistons, old style Torker Intake, 650 Spread Bore Holley and how long since you heard this one... lol... aprox. 270 . dur. lift 480 Racer Brown Cam. Now this little engine spins like a top and would like to use it as is but I do have a fresh set 340 X heads off my 340 that I'm not using so would there be anything to gain by putting these on the 318??
