Mopar performance 360/380 hp crate motor

The camshaft in the 360/380hp crate engine was actually a huge compromise due to the stock valve retainer to guide clearance issues. The heads are completely stock, but they had the spring and retainer upgrade. The camshaft was not aggressive down low. Swapping just the heads won't work anyway because it should be a Magnum based engine with Magnum intake bolt pattern. Then it will require new rocker arms and pushrods since the Trick flow heads are LA based.
The best value with that crate engine is either run it as is after a good inspection, or get a better camshaft grind specifically for the intended use and combination.
Oh, and it would be down a little on compression with the trick flow swap since the Magnum heads it should be equipped with had smaller chambers than the Trick Flow.
