Default Am I maxed out with stock heads?

Need some opinions from you guys. Currently with everything in my sig, I am putting 403 to the ground with the stock heads. Can you guys see anything else short of heads that I could do for more power? Nitrous is not an option, neither is a blower. Wanting to stay N/A at this point. Just trying to make sure spending money on the heads is what I need to do now. Thanks in advance <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Dont see a sig, but yeah, 403rwhp N/A, stock displacement, no power adders is gonna be close to maxed out for now. Electric water pump and tuning would be 2 things that might help, but thats about it.

You could maybe try a different set of long tubes as well, some believe that the SLPs may not be that great in all applications.

Yeah I thought about that. Was looking at the Dynatech stepped, but not sure about the leaky slip on collecter. Also, it would need to be a good gain considering how much of a PITA the SLPs are to get on and off. Any other thoughts on headers or anything else?

Cats are gone, got the SLP cold air.

Ron - I ended up not sending the heads to MTI due to a slight family emergency, which cost me about $1500. I'm waiting on the old tax refund now to get my plan back in action.
