I am installing a set of e7te heads on my 92 5.0. These heads have 1.94 and 1.60 valves, have been ported on the exhaust side and gasket matched on the intake side. My question is will I have any piston to valve problems running a B cam with 1.7 roller rockers. B cam specs are 224 dur, .480 lift w/1.6 rockers. Should be .510 lift with the 1.7's.
