The cam seems to work great, I would have had the heads milled slightly but the piston to valve clearance was very close. It pulls hard all the way up to 6200, I had to raise the idle up a bit, other then that, I couln't be happier.

I love the cylinder heads. If you have heard how TFS used to install crappy valve giudes, they changed that so don't worry. They flow 250 cfm right out of the box, for $1050 its worth it. I could also run a bigger valve size since the valves are centered over the relieves now. Another selling point to me was how they can be ported to 320+ cfm, So when I get my 408 short block from DSS next year, I will have them ported to stage 3 for $1000.
