yep, IV dampner. Might be right on shift points. Will play around with them.... if i cant figure it out... will consult an Allis Chalmers service manual. Lol
I have less lift, less head and less header than you had. Dont expect mine to run anywhere near as good as your’s did..... we will see. If its a real dog i might entertain a header swap, but these little ones i have fit so darn nice.
A local guy boogered up the short turns enough that air gets turbulent past 550 or so on these heads. Guy who just worked them knows what he is doing They dont flow the big numbers but my guy said under the curve i am going to be very pleased. Just have no experience with such a head.
But i did go almost 119 several times with them much worse than they are now, and on a 10 to 1 360.... so i have some hope.
