I have been running a T1 cam & stock heads for roughly 2.5 years. Through that time I've broken CC941's and K-Motion K750's. Along with the cam installation I added an oil temp gauge to assure I was reaching at least 180* oil temp. I've broken springs on both the exhaust side and intake in 12K miles. I think the main contributing factor has been morning starts below 45*. Everytime I've broken a spring it has been cold. The car gets driven between Apr-Oct.


Is there a spring "today" that is the end all be all of LS1 valve springs??

I would like feedback because I've been out of the game a while and see Isky mentioned along with others.

Thanks for any help in advance.
