thats only for flat tappets, roller cams/lifters require no break in.

Uh oh
Do you know what that means?
That means it's time to punish the tires
But if you swapped heads, they do require a short break in period for the valve guides. Its also a good idea if you install new non-roller rockers that use a sled-fulcrum (i.e. factory style)
roller rockers require no break in period! drop the hammer now!!!!!!!!!! lolI can't seem to find any info on this, just wondering if there's a break in period for Ford Racing lifters? How long do i have to wait before i can drop the hammer?
Eh, this wasn't your average by the book head swap....it was straight out of the redneck how-to book....reused head bolts and all. As long as it lasts until i finish my other engine, i could care less. It's running like a bat out of hell right now so i can't complain.
Now i just have to retorque the stupid header boltsF'in MAC headers FTMFL
SS ARP header studs will take care of that. Not cheap though
