first - i've searched and read until my head is ready to explode. so here goes anyway!

NEW plan (at least for this week) is to do the 2.4 swap in my Lbody charger using my 555 tranny, smec/sbec electronics with a distributor swap and my holset he351cw turbo. Questions are:

1) will i need to use the 2.0 420a head to flip the intake/exhaust to get that turbo setup to fit or is there an aftermarket (or even stock setup) exhaust mani that will work?
2) depending on the answer to 1, does that limit my 2.4 block options, i.e. if i need the 420a does that only fit on certain block years?

i know there is some fabbing needed to be done with motor mounts, turbo oil lines, starter, etc but i need to start the hunt for a motor/block. the two main JYs i checked today have NO 2.4s at all so when one does roll thru i want to be ready to snag it. if need be i can fab up the intake/exhaust manifolds if necessary but would prefer stock options preferably.
