I know this is an old thread but thought I'd add my .02 ... If you are stock, I would NOT delete the IMRC's, they give our b headed cobras MUCH needed torque in the low rpm band. Unless yours are not functioning (Have someone rev the engine above 3250rpm and you look behind your intake and see if the cables engage to open the IMRC's). You are much better off, if they still function to actually delay them opening in the tune until about 4000rpm, you will get a much better torque curve.

Here's a link to some great information regarding the differences in cobra 4V heads: http://www.svtperformance.com/forums/sn95-cobras-24/668455-head-questions-answered.html
