I have Victor Jr heads as well. Just the cams are different. 235/238 @ .050, 299/302 dur, lift I=.573 E=.582, LSA 112, 10in of vac best case.
Timing at 12deg initial, all in at 3000, 36deg full.
I only switched the primaries jets, rods,
#4 on the tuning plot page 33 of the tuning guide.
part#1424 (.089") primary jets
part#1445 (.065"x.047") rods
Just switched yesterday from orange (stock 5hg) step-up springs to yellow (4hg) to see if the orange springs are lifting the rods and adding to the rich.
Have not driven yet.
Linkage: Holley Sniper dual quad kit. Use the 7.25" rod. for the Price intake, 5" will work on the Edelbrock intake (I think)

Linkage bushings: 2 each kits. You only need the washer and step bushing in the kits.

I use heat shrink on the rod jam nuts/shaft to prevent loosening.
