I'm looking at some stock cobra cams from an 03-04 Cobra to potentially use in my 94 Teksid block 4.6 (MK VIII). Would these work in my otherwise stock heads? I'm just looking to warm up the motor with flat top pistons, headers, tune, etc., And I think some Cobra cams would be a little hotter than the stock units, but damn aftermarket cams are pricey. Stock cobra cams would be a fraction of the cost. Thanks.
