also wondering about the dart heads too, in the latest chevy rumble they had a pic of the lt1-lt4 pro 1 heads and they had guide plates on them, I was wondering if those are correct guideplates for our cars or if they were just sbc ones.

The valve spacing on the GM LT1 heads is slightly different than gen 1 smallblock heads, BUT aftermarket LT1 heads are all just converted gen 1 heads, but converted I means usually they retool at the factory to make an LT1 head using existing ports and chamber, I do not mean converted after the fact.
From memory I think the Darts as with most of the aftermarket LT1 heads have a big 62-4cc chamber, again this goes back to the fact they are basically a gen 1 head tweaked to work with the LT1 intake pattern and reverse flow cooling.
One guy who occassionally posts here has run them and I believe they ran what mildly worked GM aluminums ran.
IMO do not bother with them, but what do I know?
