The Ford Barn - View Single Post - Relieved stroker motor with Ford aluminum heads

I am in the process of starting a 40 ford Pickup rebuild project and am considering building a stoker motor from a factory relieved block. I have read a little of the comments on here about the pros and cons of them . My plan is to bore the block to 3-5/16 and use aa 4-1/4" stroke crank. it will be ported, and have the usual things added to it but I do have to use the original type carb, distributer, and a single exhaust. I am aware of the relieved block having a slightly lower compression ratio, my question is, would the Canadian ford built heads help? I can't find much information on them . I don't want to use aftermarket heads for this project since I want it to appear factory. Is there any advantages of using the relieved block? I was hopping it would breath better? I am looking for someone with experience with them both ways I guess. Thanks
