BBC head ?
 

This is just a bracket ride but theres just to many wise people here. Building 509 4.500 - 400 - 6.385 solid roller 255- 260 aroud .680 lift. I have been looking at AFR 290 these have 112 cc . My weisco pistons are 10.4 with 119 cc so looks like I gain compression. How do you feel these heads would perform. Car is 3460 with iron heads, 400 hydro 4500 stall, 4.11 and 28- 10.5 Thank you all.
