isn't the proper break in procedure to drive it to the beach then let it sit there in the sun all day, drive a few miles, let it cool off for a few hours outside a nice tavern then a night drive to home? If its not don't tell my wife, thats the standard break in for any new part.
Since there is some disagreement, could you specify....
Are these dual springs with a flat steel damper? Or, are they single springs with a flat steel damper? Or are they just dual springs with no flat steel damper?
Also, what is the open spring pressure?
IME, and this is limited to solid lifter flat tappet camshafts with under .550" lift, I've always broken the cam in with its ultimate spring package and have noticed no reduced life/failure in any engines done in this fashion. I do understand the wisdom of using a lower spring pressure for break-in but guess I've been lucky *G*
Your application is fine to install the complete package and run it in ,,In cases where I have a triple spring set up I send my cam and lifter combos(whn I don't have them grind the cam for me) to cam research and they run them in on their cam dyno ,,It is a neat gadget to guarrantee cam lifter life with out the fear of contaminating an engine
