One of the facilities doing testing on these heads recently used our 195cc, 2.02"/1.60" street/strip version of our heads. They were used on a 383 stroker, 10.5-1 compression, .040" quench, 242/248 .540"/.560" 110 LSA hydraulic roller. Our heads on this combo netted 517 hp @ 6200 rpm and 493 ft-lb @ 4800 rpm !!
