So I'm in te process of assembling another motor for my marauder. I have factory short, and will be bolting up a set of brand new ford racing fr500 heads and an eaton sc. Now I know the fr500 heads have updated cooling passages and such. Now ford suggests I use the head install kit from ford racing (link below)

Now the kit has stronger head bolts , Matching head gaskets and a new dipstick and such. What worries me is The note
* * *NOTE: Will not fit 2003-2004 Cobra and not designed for use with Supercharged or other forced induction Engines.* * *
Now this is what scares me. Why would they not suggest using this kit for s/c applications. Are the head gaskets not strong enough? Should I use cobra gaskets? Obviously I'm going to check fitment and make sure all coolant passages match up. Now this also raises the question if I can use my fr500 heads with a blower application? I don't see why not and can't see what difference it'll make. Ill prob call ford racing tomorrow to double check. But any one have any idea? I havnt bought the kit yet . Just want to make sure I'm not Wasting my money
