I bought my newly restored TS with only about 450 miles on a re-built engine, and immediately had a Snyder 5.5 HC head installed. I have stock ignition and carburetor and set timing by the book. Mine runs great with the spark at about the 9:30 position.... not sure how many clicks that is, but it runs very well in that position, with no pinging, even going up pretty good grades. On the freeway at 55-60 (with o/d) I advance it to about 8:30 and it runs very well. I always run with the gav about 1/4-1/3 open. There was a very noticeable improvement in acceleration and pulling power with the Snyder head, especially nice in the heavy Town Sedan. Something must be wrong if you have to retard the spark so far that the power gain is lost.
