    yep it has been done many times just use the rect port gaskets .if woried then you could close the roof down with A&B putty but in time it will work off and come down . i have tig welded the ports down but abit of work . so just bolt it on less you want the ports the same size and that would be $$

    I know it's been done but I also have heard it's not good. It will result in intake flow reversion. Won't hurt anything but performance IMO ............

    I agree with Pat. Won;t hurt a thing,heck on the sprint car we are running hilborn injection that was port matched for a set of brodix heads ( big big ports) that setup is bolted on a set of stock 305 heads and I gaurantee ya my right foot and the guys behind me can't tell of any problems.. Now keep in mind if I was Steve Kinser or such I would want it right.
