Head and cam selection help for 440

Ive seen them but do they outflow the stock 452 without porting enough to see much of an improvement? also, should i stay open chamber or go closed?
Check out the Edelbrock E Street heads 1149 for a pair with 30 off from Jegs. 1119 with free shipping better parts. Send them to PRH to be checked out. Or just save up for the trick flows. If its just a street cruiser I'd leave that cam in it. With your shortblock, intake and some decent heads I would think you should be in 450-475 hp range.
