Biggest mistake ever- lunati cams

I have a Lunati 10200704 and the springs that go with it in the 340 in my Duster. You have to machine the heads to accept the double springs, that's true even with the mopar 308 heads I have on my 340. The factory heads were not cut for double springs. Then you have to check, and possibly machine the spring pockets or shim them to get to the proper installed height. I'm not sure if the website still says it, but Lunati's springs used to have a disclaimer posted that you would need to have the your heads machined to accept the double spring set up.

I don't see how this is a Lunati problem at all. You bought springs that don't fit your heads. You either have to make them fit, or you have to buy different springs. Which you probably could have figured out just by looking at the published specs.

And while I don't condone the lousy customer service, what exactly is it that you need customer service to tell you? The Lunati springs require the heads to be cut for doubles. Then you set the installed height. The only sell the springs they have listed, so, if you don't see springs with the specs you need on their website they don't have them. Beyond that, they're gonna tell you that you need to get to the proper spring pressure for that cam, which again is already listed. This is just what you have to do when you install any aftermarket cam- you have to measure the installed height, check the spring pressure, and make the modifications necessary to get to the proper spring pressure.
