Perhaps you could explain your expert logic in coming to this conclusion? Did you even attempt to isolate the "tick" and determine what caused it? Did you inspect and measure the cam lobes to determine it was a bad cam?

I can tell you what cam is not a good choice for your application … the one you have that requires octane booster to keep it from pinging.

"....and the cam was " recommended" by Edelbrock."

Similar to Comp Cams just regurgitating the use of the 995 valve spring for a great number of their cams ! In the catalog and a guy sitting in a work cubicle answering the phone.

I inspected the lifters as requested by Lunati. They didn't show any signs of being messed up. Then I sent them their cam back.

I'm the one who actually did find the tick. I know it was the cam and lifters because I fixed it by switching the cam.

One thing though;

I have yet to hear of anyone who used these heads Sam, Firebob, and I have with the 703 that didn't have a tick.
