First thing I would do is delete the IMRC cause theyll be gunking up soon im sure. You can just buy the delete plates from MMR or just removed the butterflys from them and have the holes welded.

After much debate and research what to do with mine I decided on the following:

'04 head swap off of an Aviator (salvage yard - $465 shipped)
'01 Cobra intake (got from cobra_drifter here in the classifieds - $286 shipped)
Forged piston and rod combo

I'll be swapping my B-head intake cams to the '04's before they go on the motor. As for the piston and rod set I'll be giving the compression a slight bump to right around Mach1 levels. In the real long term I plan on throwing on an IC Kenne Bell blower (I'd prefer a Whipple but that would require a Termi pulley set-up swap too. . . Might still do that). But that'll come only after suspension stuff (phb, ta, sfc, etc)

I've contemplated c heads as well, but after some heavy research of large boost applications ported b heads > ported c heads.

Agreed uber. The C and '03/'04 heads will flow less than the B's. However my choosing the '04's was due to the fact that there is no intercooled positive displacement type blower for the B's. I know there are plenty of intercooled centri types out there but I'm partial to the sound of a twin-screw.

These are the types of things the OP needs to consider when planing his build.

Gotcha, if you want a PD blower B heads are a downfall

Crysalis 01, I noticed on your list of mods that you have the Steeda Tri Ax short throw shifter for your 98 Cobra. How do you like it? I was looking at some short throws (it would be between the Hurst and Steeda) but I don't really know which to choose from.

I like the Tri-ax. It performs very well, but if you're looking for other options MGW makes a fine short throw as well.

Totally agree. you can afford to buy nitrous + suspenshion mods with that budget. Do that and you will be walking all over the newer muscle cars.
