Who is the Best Nailhead timing chain and gear set manufacture?

I thought I would get a good set from Egge Machine. So I ordered and received a cam gear, chain and crank gear from S.A. Gear Manufacturing Company - Automotive Timing Components out of Bedford Park, Il.

The cam gear appears to be cast and not all steel. It lacks the proper dual tapped holes to set my fuel pump essentric into as well. The teeth edges have brittle edges.

The timing chain looks like a japan made one I had some years back with that tell tale hue to the metal and smooth construction. The link pattern is minimal.

The crank gear appears all steel and of good construction.


Has anyone used S.A. for their replacement timing sets. Has anyone heard of problems using the S.A. Gear and Timing Set. I few engine rebuilders have said that they had problems with indexing the cam and S.A. was off. In addition the timing roll marks were off as much as 1 tooth between the cam gear and the crank gear in one example. Rollmaster appears to have a good set and was on at time of the install. No index problems.

Could anyone shed some light on these issues as well as who makes the best timing gear set out there and why are they the best.


Thanks in advance.
