The CS is a 0.0397 short tip.
For reference, my '83 TR had CP's which are 0.0567 medium tip on a R hanger.
The tip's range from about 0.1000 to 0.0300.
Roe recommends Long tips for drag racing/WOT. They get thinner (richer) quicker.
The richest hanger/rods I have found in the junkyard are F-DS. The DS's are 0.0337 Medium.
The thinnest long tips are 0.0397, either AX or BB.
Somebody has this chart posted on the internet.
