Yeah, I see what your saying Hank about the comparison between a stock port with or without the bosses tapered vs. a port with the bosses removed with no lump installed. Yes, the port that still has the bolt bosses will provide better velocity than the one with them removed but no lump installed. For the street, yes that is a true statement, and like Leo also says, unless upgrading to a lump port, leaving the bolt bosses is better.
The OP seemed to be eluding to the fact that from what he had seen was leaving the bosses in place was better than installing lumps for the street. That is untrue and what I was meaning. Sorry for any confusion if thats how you took it.
