Hey Jeff; I just was not sure if they would work because of a differant angle or something And thats what I am looking for is more compression and HP.
They are not for high perfomance but more to give me more grunt when pulling a trailer thru the Nevada mountains. I know where there are two set of the 67 289 heads for a good price and they already have screw in studs and guide plates. Not sure if the roller motors have harden push rods or not, so I may still need to buy some.
I am not really looking for bigger valves like I said just a little mor grunt power on long climes. Thanks Kurt
