Barry, thats why I was asking. All the Fentons, B&B, Barker, etc. I have seen are only for the intake. Thats why I was curious why Thomas had rockers for the intakes AND exhausts. Did they know something these other companies didn't!? J.H. and dabond, I apologize if it was a stupid question, must be tough being perfect.

1955 Chevrolet 210 2 door Sedan
a 30,000 mile UNMOLESTED original, now my daily driver! Original 6 cylinder with a rebuilt '66-'69 Saginaw 3-speed Overdrive. Synchro low! Otherwise, everything original down to the spare tire. Interior is like new. Needs paint, but absolutely zero rust.
