Groundhog Posted April 10, 2016 Posted April 10, 2016 I've heard mixed reports about valve springs breaking when using a high lift cam, In particular the inner valve spring. What type of valve springs are people fitting? I have a cam with 0.490" In/Ex lift. Quote
C.A.R. Posted April 12, 2016 Posted April 12, 2016 With that lift, Is the cam a works 72deg item? If so, STD valve springs will be fine. Quote
Groundhog Posted April 12, 2016 Author Posted April 12, 2016 (edited) The cam I have the option of using is a TIGHE 492C. It comes already fitted to a reconditioned N42 head.I need to decide whether to go with this cam or change it for a 72 degree item. http://tighecams.com.au/cars.htm Edited April 12, 2016 by Groundhog Quote
dat2kman Posted April 12, 2016 Posted April 12, 2016 (edited) Do you mean tighes 462c grind, as per their tables? 492 s not shown. For a mild grind, the Performance brand springs are fine. Does it have springs fitted? We can pull them out and comare stock to the Performance RR4' I have plenty of both! Edited April 12, 2016 by dat2kman Quote
