This is what I do. Additionally, I take the inner springs out for break in. No problems after several builds. The cost of oil is CHEAP compared to any engine build. I also used to run low/non detergent oil. Switched that to vr1 conventional and changed the oil just like I would for a cam break in. Peace of mind is worth the cost alone.

Another good idea that just adds a little extra insurance is to place a strong magnet on the oil filter (such as one of those "Filter mags"). It will hold on to the fine metal particles from the cam break in and won't let them circulate into the engine.

So do you use air to hold the valve up or do you remove the head to replace the springs?

I see the comp recommends this method. What is the best way to do this ?

I was also told to run the engine for only 5 min at a time let cool offcomple the run 5min repeat until you have 30min break in time.

What is working and what is not on engine break in theses days?

As far as oil I use Brad Penn ( the green oil)

Thanks
