    I've been seriously thinking about selling my nitrous kit and getting me some worked heads.... I know it will be faster with nitrous but eventually the nitrous will break something sooner or later especially if I get greedy with a 150shot.. I have ran a best of 12.5 N/A with stock heads, do ya'll think with some good worked heads I can get a 12.1 or 12.2 N/a??? if I can get a very low 12 sec run n/a... I would really consider that route....

    what is ya'll's opinion??

    thanks...

    Id say go ahead and do the heads. I mean cant you go back to nitrous after the heads are worked too? Then you could break into the elevens. You could probably even get the 11s with just heads. I like to shoot high for badass trucks like yours

    Get the heads, you can always play with the happy gas

    Go big with the heads, big enough that it still can be driven daily....

    Add some awesome heads like the ETPs. You&#39;re going to pay through the nose for them though. I would wait until we start seeing some results from the L92 heads and intakes. Those things are flowing some incredible numbers and I can&#39;t wait to see some dyno results.

    one thing I am not worried about is horsepower..... I like to see some 1/4mile times.... does anyone know of someone that has installed heads and that they have gained .2-.5 off their e/t??? I want track results not rwhp.... from what I read I only see about .2tenths off their time, I dont know about ya&#39;ll but .2 aint worth almost &#036;2k for me?? or am I just asking for too much??

    The ETPheads are nice they are an 11* head which is what contributes to their damn good numbers. AP all the top dogs on tech run either ETPs are AFRs. Both are oging to run you 2200ish. I say work on your suspension and spray the piss out of it then do the LS6 conversion then do heads last. All the HP in the world aint going to help if you cant get it to the ground.
