Getting Head After Hot Cam
First, thanks for all of the information regarding the hot cam advice. After the hot cam install, what would you recommend as far as getting some head.....ummm, er.....cylinder heads that is? Should I just port and polish the stock ones. What aftermarket heads match perfectly and maximizes the hot cam swap? Do I need 1:6 rockers to add additional performance?
I do intend to install 3:07 gears, and slightly better flowing mufflers in addition to the cam swap. (Also a good tune). My C4 is an LT-1 with 99,000 miles, automatic.
Thanks in advance!!

If your going to do all that, just do it at once. Why limit yourself to the hot cam if you plan on going with different heads?
I'd say get your heads worked over professionally, or buy a set of AFR or Trick Flows and then pick a cam to compliment their abilities.

If money is an issue, I'd suggest going with a high stall convertor before fussing with the heads, in order to get the most out of driveability.
After a few months when you're bored with the basic improvement....THEN I'd do the heads and exhaust.

Buy a $30 compression gauge and do it yourself. It's not any harder than changing spark plugs.

If you want to wake the car up big time do the gears first, I put 3.73's in mine and a 2800 stahl and holy **** what a difference that made.
If that's not enough for you then you can pick a cam to compliment the higher stahl and the new gears. I couldn't believe what a difference
those two mods made. The car will feel like it picked up 100 horsepower. MR.MOJO was into the mid 12's with a 2800 stahl and 3.45 rears on drag radials, stock cam, stock heads. Just my .02
