Wait or not to wait, that is the question?

For LS6 springs You shouldn't need Double roller timing. Right?

I'm not entirely sure.

[Darkshadow188]

LS6 springs are rated at 90#. A double roller would not really be required as your timing chain and tensioner can still handle that load. DRT is more work that you would HAVE to do, especially with LS6 springs. If you were using 130# springs, DRT would be useful.

You dont need a double roller, tubular manifolds will give you just as much power as headers as long as you are NA, and you might be happier if you spend money on suspension before you get into your engine.
