have to change springs or anything on 243 LS6 heads with TR224? my friend wants to change his cam to a TR224 and got his hands on a good set of 243 LS6 heads he was wondering if the springs and stuff on the heads were good enough for his soon to be new cam or will he have to change springs etc?

I'm running a 224 Comp cam with .581 lift and 918's on new 243's. I would swap springs for any deviation from a stock cam. It is worth not haveing to deal with a broken stock spring. Also don't forget to get a set of hardened push rods to handle the stiffer springs. Just my opinion.

actually, the yellow Z06 springs are rated at .580, there's one or two other members on here that are running the TR224 with Z06 springs. This weekend or next, I am installing a TR224 with those springs and see how it works out.

I have read mixxed reveiws as to whether or not it is a good idea to run the yellow springs with a higher than stock lift cam but everyone for the most part agrees that the 918's are a safe way to go. Why chance it? If your gonna run a 224 cam then just get the 918's and be done with it.

The lift is one thing to consider but the ramp rate (how fast the valve opens and closes) is another. The ramp rate on the TR224 is much more aggressive than the stock or hot cam. But hey its your engine...
