M1 SP vs Air Gap

Don't want to steal the thread,but since everyone is talking, just a quick question. I have an LD4B and would like to use it on a 340 with x heads. I'm going to run a thermoquad. Would I be better off to run an adapter or open up the intake so the TQ can bolt direct. I'm after low to mid range torque. Also, if I port match the intake to the heads, will it be the same as an LD340?
Thanks guys.

The intake will work fine on your 340, especially if you port match it. I dont think they can be opened up for the thermoquad like the LD340 though.
