I just had a spring break on my setup.
I have L92 heads with the PAC 1518 springs. I bought these heads used which owner stated they had about 1k miles on them (they were clean and in good shape). L76 engine.
I installed them and a cam of the size of 231/236 .641"/615" 112lsa, and engine ran ok for almost 1 hour of total run time, and then I got a noise and found a broken spring.
Is that cam to big for these springs. Any idea for cause of failure?
Thanks

You need something like the PRC Double .650" spring kit.

I see the PAC 1518 springs are rated to .650, so I figured I was ok when I bought these heads..... Also, it was an exhaust spring that broke - I see the intake on this cam has more lift than the exhaust...
Thanks Jason. I will likely be calling you guys soon to take you up on that!
