Well I think the best head for the money is the TSP/PRC stage 2.5 5.3's, which is why I bought them. However, you mention N2O in your requirement which generally indicates the desire to go with something with a thicker deck for less chance of loosing the head gasket when ingesting larger doses of gas. One option to consider would be the Terminator heads which went for around $1800.00 the last time I checked. These are cnc'd from the Edelbrock castings so they have the thicker decks that you can only get from the aftermarket castings. That said I would most likely opt for the TFS's if I was going to spend that amount of cash anyway. Just be aware that with the TFS heads you will also need aftermarket rockers as well.

match your heads to your cam choice. just because you buy the best heads does not mean you have the best combination. also are you going to just race the car or will you see time on the street? dont get caught up in hype of these are the "best" parts
