When selecting a stage 2 head. which of these is better suited for a street car that will see some track time.
I know absolutely nothing about these and am trying to learn before I make the leap.
Is it better to purchase them assembled or bare
short block is a 455 bored to 462. stock crank and rods. Ross pistons 9.5-1 compression (balanced)
I have iron heads now with stage 1 valves and springs and TA 1.6 roller rockers.
Can I use anything from these heads other then the rockers ?
will my HP850 4150 holley be enough? ect. Headers I know need to change.
any insight to the upgrade is appreciated.
OR...should I just start a new motor from scratch and run this till it's done. lol
I am my own worst enemy.
