18* Head flow numbers inside = )
well finally i have heads that flow great.
Brodix 18c
Lift intake and exhaust at 28" drop
.100 64.6
.200 129.4 128.2
.300 198.1 191.4
.400 262.0 232.5
.500 314.3 252.0
.600 347.9 262.2
.700 373.9 267.2
.800 378.3 270.0
.850 378.7 270.2
Im very happy with the results.The heads flowed within 2% of advertised. The exhaust outflowed my brodix 10x unported on the Intake side lol.
the only thing i have left to do is pick a cam.Im thinking of going with cam motion.What cam and/or cam company do u guys recommend???(anything but comp cams)

Brodix 18* heads are nice. A bud built a simular thingie using these heads. I know you don;t like Comp cams but this is the cam he used. Worked very well over 700hp N/A and 1300hp on the juice. 309/322
advertised duration and 272/284 at .050. The
lift would be 704/672 with a 1.6 rocker and set
it up on a 112 lobe separation.
grind number is 309-6/322-3
SR112. it's a custom grind. If you want a small base circle you have to specify this. ( 400 ci)
Sounds like a lot of cam but a large ci motor eats it up pretty quick.
Can't argue with the results.
