This may be something you already know, but if you are doing the work yourself, be careful when breaking in your flat tappet cam. It is hard to get motor oils currently that have enough zinc to protect flat tappet lifters. The stuff harms oxygen sensors and the oil companies have taken it out since most OEM engines now have roller tappets.
If you are intersted, I put together a video on breaking in your flat tappet camshaft on my website. You can see it at
StreetMuscleAction.
