Head springs???

[supersean]

Can someone please tell me what is the maximum lift stock springs can go to in a stock 3.8 motor?

Re: Head springs???

I don't know where they will fail but I do know that the retainer will hit the valve guide somewhere just past .520" or so.
So I would say that .520" is the limit, after that you need the guides milled down, and then I would get some other springs.

i believe the kit has comp 105's. but im getting the exact same noise at upper rpms that others posted. so im looking for a fix.

i have a set of stock retainers and locks that i could use.

not a thread jack, but the timing of this thread is perfect. :banana:

Comp 105s should be ok.
Just for safety, you can pull the front cover and check it out.
That about all I can tell you.
