You asked for it, out of box. int. .086"/46.5,.173/90.2,.259/136.3,.346/176,.433/188.5,.519/185.4. exh..073"/33.7,.145/71.5,.218/103,.290/129.6,.363/140.8,.435/146.7. Figures are at 28",(converted).Int. port = 2.36 sq. in.w. 1.73" valve dia. Exh. port = 1.96sq. in w. 1.45" valve dia. Flowed through a 3.72" bore and exh. flowed with 4" stub.Chamber width is 3.56", reportedly 32 cc,not verified. Valve inclination approx., 20 deg. not verified and 1.660" centerlines. Stock "Rover" flows were listed on 3/27/10, this forum. sbc. valve cover with bolt holes moved.I will be using (6) bolts per bore, NO Ti valves,(seats too hard and their stayin). Lookin for 220+, on intake side. We'll see. Good Luck, roverman.
