Ken, I know how to whittle on metal, I want to know if the flanges that bolt to the head are any wider and thicker, aftermarket intake vs OEM, so once I do a port match, I'll have enough metal to drill for locating dowels through the intake and into the head without destroying the o ring groove, thereby compromising the seal. If the aftermarket intakes flanges are 3/32nd" wider or more, I can do it, OEM, I won't even go there. I can't afford to buy a set, just to find out, I have presents to buy too.
