the brodix that i have got very old casting and the new valves and guides will cost me alot there was nothing wrong with them other than the valves and guides leaking oil in the cylinders but I want heads that flows like a champ from .500" and the AFR 220 are perfect

I'm running a GM Bowtie block stroked 4 inches and bored 4.125 inches, 427 cubic inches, hydraulic roller with solid lifters 562/571 248/258 @.050 112lsa, GM Vortec Bowtie 215cc large port heads with 2.02 and 1.6 valves, compression is 12.5:1, 850 cfm carb, Super Victor 2926 manifold, 1 7/8ths headers, 700r4 transmission, 3000 stall, 4.56 Moser 12 bolt, 29X10 slick. The car is made for spray, N/A I ran the best of 11.3@121. The 10.6@128 was with a 100 shot. I only got to run the 125 shot in the 1/8th and picked up 3 mph and 3 tenths(6.80@101 to 6.50@104. The car doesn't hook very well, best 60ft 1.45. I feel that the bowtie heads are just too small for 427 cubic inches, that is why I picked up a new set of heads plus the price was right. I'm hoping for significant gains with these new heads and more lift from the 1.7 rocker arms; although, taking some weight out would help a lot.
