Definitely not 2.02/1.60. Usually aftermarket performance heads have that size valves. My Fast Burns have 2.00/1.55 valves. __________________ Black 1991 Z28 -350ci ZZ4 shortblock -GM "Fast Burn" aluminum heads -LT4 intake manifold (modified and ported to fit Fast Burn heads) -LT4 Hot cam w/ 1.6 roller rockers -T56 six speed transmission w/ LT4 clutch/pressure plate and Pro 5.0 shifter -3.73 gears (soon to be installed) -custom burned eprom -LS1 28 lb/hr injectors -Hooker shorty headers -Corvette ZO6 front brakes -lots of suspension upgrades -LPE 3.5" aluminum driveshaft -17x9 SS wheels
