Proper valve spring/camshaft break in?
Proper valve spring/camshaft break in? I am going to install new patriot gold dual valve spring kit, tr224 camshaft, pushrods, ASP pulley, and ported oil pump this come spring. My father is doing it at his auto repair shop and I am giving him the ls1howto.com guide as well. Anyways whats the proper procedure for breaking in the new valvesprings and cam? Any hints, tips, and suggestions about the install and aftermath is greatly apperciated and what I am too expect. Thanks
Roller cams don't need to be broke in like a flat tappet cam. Basically cover the cam with eng oil and install it. For the valve spring I believe it is recommended to heat cycle the springs a few times before reving the engine. After that you will want to let the springs warmup before driving the car(high rpm) each time you start it. Stronger valve springs are brittle when cold.

After installing my cam, we revved the engine up to 4k and held it there for like a minute.
Not even ten minutes later we pegged the speedo.
That's goes to teach you something right there. TSP 231/237 w/ PRC gold duals. Car's been running fine now after 1000 miles, and I rarely wait until operating temp to go high up in the rpms.

There is no heat cycling of springs. . period. Springs are shootpeened and heat treated before they leave the mfg. Your warming of the engine does nothing.. . .Period. . .Nada....This comes from the engineering department of Associated. What is important is to get the engine oil temp up to operating temp before you put your right foot to the floor. The hardest thing on an engine is reving it when it is not up to operating temp.
So make sure engine is up to temp then have at it.

After reading some good opinions on both sides, here is what I've concluded. It is your engine and your $$$$ for repairs. I am on the 3rd heat cycle after a 231/237 / comp 918's install. I'd rather be safe than sorry. Plus my car sits all winter in the garage anyway so I don't really mind wasting the time.
