5.9l magnum swap questions

I'm running stock heads and a cam with similar specs. 230/234 @.50 .506/.513 lift. 106 cl 110 LSA. Air gap intake, Holley 750 DP and cheap headers. Ran 7.88 in the 1/8th first time out.

So I agree with doing a compression test in the junkyard. If that checks out i would run the stock heads. These magnums are stout with just the cam and carb swap. Good luck.
