If u are set on getting those heads Done, get a hold of marty warden in north carolina, he did my first set of iron heads on the grand and we all know how that car ran! You still need to verify your cam timing tho, otherwise u are just shooting in the dark!!

Crower grinds the 60916 cam with the intake centerline at 112 degrees.The camcard suggests the cam be installed at 108 degrees intake centerline. If you are 1 degree off you likely wont see a change on your time slip. TWO degrees of timing change almost always shows up on a time slip. FOUR or more degrees off will absolutely be seen on your time slip. ALSO keep in mind your timing sprockets were not made by Crower and not referenced the same plus chain slack etc. all adds up to tolerance variables. Not to mention possible install errors. You are likely a minimum of 4 degrees off... You could be 7-15 degrees off. Until you degree it you will never know.
A degree wheel, timing pointer(coat hanger is cheap. I made a tin pointer that bolts to block and made it so it goes back exactly where it was if you unbolt it to make a timing change), a dial indicator and a mounting base are not very expensive and you are likely to use them in the future. A Mopar advance key kit doesnt cost much either. Get it done...If I was closer I'd come over and do it for you...FREE |

Does the Drivers head need to come off???? I have dial indicators, work in a machine shop.
I have a spark plug guts removed the guts and tapped for a bolt. I also have a degree wheel. Sure would love to get my heads off for some serious checking. I am finding it difficult to see investing 600 to 700 in a set of cast heads. But for all i am doing ill be happy with the investmant. |

You can do it heads on or off. A solid lifter or two is nice but you can make a hydraulic solid easy enough. you can check directly at the lifter or at the valve.

Rich while it isn't necassarily ideal. i did this a few yrs back here is the link, read it when u get time . it did tell me pretty much what i needed to know, and if i remember right when we pulled that cam out we did actually degree it and it was 105 i think? So it was pretty accurate method to try.
