Regardless of brand, I don't care for the timing gears that use a slot to locate the cams dowl pin. I prefer the timing gears with the drilled hole for the dowl pin.
One reason is the slotted versions have no way of correcting the cam timing. The sets normally do not have an multi-position crank gear.
With the timing set with the hole, the hole can be drilled out and offset bushings installed to correct timing.
For a few bucks more, a set with adjustable crank keyways is nice to have.
The 440 source 9-way adjustable timing sets are pretty good for $100.
