    Rocker arms interchanbe with six I believe. R3 caps are larger than R1/R2

      Thermostat housing.

      R3/R4 valve covers definitely had a larger tube diameter for the caps. And yes, those caps are essentially the same as OHV Lark six caps except for the chrome. An R1/R2 cap will not fit on an R3 valve cover...at least not without a large hammer. <GGG>

        Yes. I must be mistaken on the interchangeability of the caps. I found that I still have one of the caps that I used on R5642, and measured the inside diameter. The cap is a "Seal-Tite" #804CBL and measures 1.530" inside diameter versus 1.385" for the stock R1/R2 caps. That would explain why it fitted so well and was a perfect substitute for the R3 caps. You learn something new every day (or at least should)!
