They have a deal on the canfields also, that is where I got mine. Maybe you can exchange the heads and headers for the canfields and it might cost a little more but the stage 1 canfields out flow the stage 2 Holley heads.
The only down side is there non-emissions heads and if you get the 2.02 1.60 valves and any aftermarket cam you will need to fly cut the pistons.
Mine would barely clear with 1.7 rockers and stock cam.
If you get any heads I would recommend to get the smaller valves if you want to run a big cam and do not want to fly cut the pistons.
I don't think you can go wrong either way, you will notice a difference with either heads you choose.
Good luck
