Semi-noob Crane Dual Valvespring question OK, over the past few months Ive been gathering parts for my 1st upcoming cam swap (which I'm doing with a friend who knows FAR more than I do, so I can learn from him). I decided on going with a mostly-Crane setup, including their 144832 Dual Valve springs. I have a few questions. 1st being, is there anything else I need to purchase for these for them to fit in the stock heads? And, to go with that, is there anything else I need to purchase for them to even work PERIOD. For the curious, I'm going with the 1.7-ratio Gold Extruded Rocker Arms, if that makes any difference. Thanks for the help in advance, sorry if its a dumb question! But, better a dumb question than to get the install started only to find I'm missing parts :-/.

You need their titanium retainers which fits that spring....that is all. They accept factory 7' valvelocks. I would advise you set the springs up a little tighter than Crane recommends....more along the lines of 1.750 installed height (versus 1.800). You still have plenty of room till coilbind even with .600 lift and would have better seat pressure (closer to 130 instead of 110 which is light) to better control the beefier rocker gear you plan on running. Hopefully your friend has the proper tools to check spring installed heights....you cant just install them in the stock pockets. You will be needing to shim and check each one to assure consistancy and proper height.
Good luck...

Crane doesn't make shims for the 832's, but the Comps work. I can give you a part number if you need it. I too recommend they be shimmed as Tony stated above, at least 0.030". The Crane springs are excellent, but they set up with a low seat pressure and you must use shims to obtain the correct seat pressure. Crane also makes machined locks, in my opinion, the $30 is well spent here.
What other parts are you installing, timing chain, etc.?
Did you get the Crane Gold rocker kit or just the rockers (the "a" part number)? If you got the kit, then you should be set with pushrods, etc. Also, the Crane/Vinci valve spring tool is the cat's **** when it comes to changing the springs. I even went so far as to modify my new Dart heads so I could use this tool.
Good luck with your installation.
