I hate to ask a question that has been probably asked a million times but here we go. I am opening up the ex. ports on a set of C8VE-E heads and am wondering about the lump on the opposite side of the port , across from the head bolt side. I know you can grind the head bolt side flat but what about the other side? That looks to stick out quite a bit I have never heard anything ever said about that side of the port. Also should you use ex. manifold gaskets or header gaskets to match the port openings? Or doesn't it matter? This rookie will appreciate any info anybody can provide. Thanks, JD
