How long to break in heads?
How long to break in heads? I just installed heads and cam. My question is how long should i break in the heads and cam before pushing it. I was figuring at least three good heat cycles for the springs, but what about the heads?
id just make sure everything was ok and then go out and do some pulls 
its not a flat tappet cam that needs to be broken in and i dont see why the springs or anything else would need time to break in or be heat cycled

Go to a local shop that builds race motors. They're not going to start the motor and heat cylce it three times before making some WOT pulls loading the motor WAY harder than any boat/car/truck application ever could.
It's probably not a bad idea to heat cycle it, and of course don't beat on it too much because it has new components, but you could certainly roll into it a few times to see what she has.

Whether it's necessary or not is open for debate, but I know when it's my money in my car, I'll be giving it a little time.

I finally did a good run today on the new heads and cam. Wow! My car pulls hard as hell. It was like all i was dooing was shifting going through gear after gear non stop until i got to forth. I cant wait to get it tunned, i think it will make it pull harder and more smoothly. Still dont have any times or anything but trust me the heads and cam made it into a whole new car. thanks again
