Hey Guys,
I'm running SF heads on my drag car this year. just in the pre-assembly phase here.
Got the heads back from being flycut .080 so I'm down to 48cc . So I go ahead an pull all the valves and install some checker springs in cyl 1 and notice my installed height is 1.800" . looking at my autocraft 1.4's I'm thinking this is not going to work. I need approx .300" shims under the rockers to even clear the valve retainers, let alone line up with the valve tips.
Does anyone have any suggestions or know if the new style pauter rollers will set up properly with the longer valves?
