Step up and get the tr230. That cam rocks man... I drove daily on that cam for over a year. I think you would see a good 12-15 hp gain going with the tr230. Why leave anything out on the table.
Good luck with the new heads

Just try it and you'll find out.

Now that i look at em. My numbers are better than his new heads. But I did get a set he was doing for someone else way back when. As far as I know mine are with stock valve sizes as well 
I looked at his site and my numbers are actually a little better in spots than his stage 2.5 heads :woot:

Please show me my ignorance and show me a set of his 5.3L heads that flows over 300cfm at .550 lift and close to 310cfm at .575-.600 lift through the intake manifold
