Avanti Diameter!

[mfg]

The exhaust valves in Avanti R3 cylinder heads are the same diameter as the intake valves in Avanti R2 cylinder heads.......True?

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.

False is CORRECT!......... (Pretty darn close though!)
