98 GMC Injector update kit

I have searched the fourms to no avail.
First of all I have a 1998 GMC 1500 2WD with a 305 and 4L60E.
I have heard there is a fuel injector update kit that includes the injectors, fuel spider, and the block the fuel lines connect to (sorry I don't know the name).
Is there such a thing? my pickup idles rough only when in gear, no service engine soon lite.
I need to replace the heads on it and thought I would do this at the same time but I can not find any info on it.

Thanks A.J.

As a side note any one have a good source for the heads and associated parts to do this job?

You can get brand new L31 Vortec Heads from any gm performance parts dealer or on www.summitracing.com (and others).
