So, i dug the 140's out of the shed. they have all new SS valves, new isky guide plates, didn't measure the valves yet but intake and exhaust are almost touching, new springs, 7/16" studs, no rockers, measure 68cc looks like some cleanup work on both intake and exhaust, guy we got them from was racing them on a 326, low cost install so unless there is a reason not to go this route probably going to install them. from Walace calculator looks like it gets CR up to 9.4 should give more power than what it has now. any thoughts?
