r1lark Posted December 17, 2017 Report Share Posted December 17, 2017 The Paxton specs for the R3/R4 posted on Bob Johnstone's site (http://www.studebaker-info.org/Rseries/R3R4.html) provide the R3 exhaust valve diameter as 1-5/8" (1.625"). The Studebaker Shop Manual provides a R2 intake valve head diameter of 1.6562". So, the answer is FALSE. Link to comment Share on other sites More sharing options...
