383 roller motor

for the my 73 duster i plan on pulling the 318/904 combo for a 383 and a 4 speed (when i finish getting all the parts for the swap) im sending the 383 to get machined. see how the rotating assembly looks, and go flat top pistons, alot of head work and a full roller valve train. My question is who makes the best street roller cam for the big blocks, and is it worth going stroker?

Thanks,
Steve
