Change in plans... Anybody used a "retro-fit" roller cam in a Magnum?

Cool thx guys, @66jim how much did it cost for a regrind? I'm looking at this cam from Lunati: Voodoo Retro-Fit Hydraulic Roller Cam - Chrysler 273-360 270/279 - Lunati Power I think their Voodoo roller line is pretty new, like released less than a year ago... I'm looking at them for now as I've ran the 256/262 Voodoo hydraulic flat-tappet before and it was awesome. Lunati lists MSRP for one of those cams around $300 so unless it would be a lot cheaper to get the Hughes adapter and regrind the stock cam I'd rather just get a new one...

@Lelo Dart was just reading Magnum-Swaps.com looks like they had similar success with that Mr. Gasket .028" head gasket. Stock is like .050" thick so that's a pretty good improvement. I also CC'd the chambers in my heads and they came out to 66cc, 3 bigger than factory spec but gotta run the calculator first and see what I get. Regardless as long as it's over 9:1 I'm happy, 9.5:1 would be ideal but kinda splitting hairs in this scenario.
