Valve Springs on Champ heads

[TurboMike]

Anyone have the specs for the springs that come with the champion heads? I'm running a HR .525 lift and 224 duration. The springs from the old M&A wont fit, should I use the springs that come with the champ heads or order some different ones?

They are 100# on the seat.They are only good to .500 lift on a hydraulic cam.A roller or flat tappet requires a spring change.HTH

It's too late for you. But others should be aware the GN-1's can be ordered with any spring installed. You just need to specify when ordering.

Maybe the customer that ordered the heads did...i'll check with him and see.

Thanks
