I just installed some Edelbrock E street aluminum heads and they recommend Champion RC-12YC spark plugs. These are quite long and not a lot of header clearance. Is there a spark plug with a shorter porcelain part that any of you would recommend that will fit these heads? Thanks

Check out the AC Delco equivalent plug and see if it's any shorter.

You might look at a set of ACCEL spark plugs.  They make a shorter porcelain plug that is made for headers.  I installed a set on my '79 L48 and they run fine.
