Holley heads
 

Anyone here use Holley heads on a SBF, if so let me know your e.t. and what engine combo you had . Which cam specs. do you think would work best, excluding hydraulic rollers.

Hey i use Holley Systemax heads on a 306 w/ 9.5:1 compression. To check out all my mods and the combo i am running check out the user rides under 87gt17815. The best et i ran to date is a 13.10 @ 111 on street tires. The only reason i han=vn't ran it with slicks yet is that i need a new clutch. But that is on its way. The motor should turn a high 11 once tuned properly. But its kind of hard to tune when you can hook up. Anyway the heads are awesome especially in a naturally aspirated combo.
