so my head is off my truck right now and i was wondering based on my sig. what i need to do to hit mid to low 12's i have talked to so many people about this for a couple weeks and just cant make up my mind.... i already have new arp studs what head work do i need to do and what stuff is just a waste of money and time and what else do i need to do??? thanks in advance

 

about 650rwhp your deffinetly gonna need something like a silver 66 for a turbo or twins if you tow alot of heavy stuff. some mach 6's injectors should give you all the fuel you need. and makes sure you have a billet input,intermediate, and output shaft cause to run 12's your gonna have to launch pretty hard.

 

well what kinda work should i have done on the head while its off my truck??? i dont wanna spend tooo much so keep that in mind

 

wow thats it huh??? one reply ok i guess i'll just figure it out myself....

 

I would have them check the head for cracks, deck it and cut it for o rings, put heavier valve springs in, and check the valves and replace if needed. If you can aford it a port and polish, but not nessacery. As for fuel and air, Id either get a 66/71/14 or throw an s400 under the super b. depends if you tow or not. Bigger injectors will be needed, there lots of good brands, f1 ddp ii schieds and so on. You can throw some nitrous at it with a small turbo and get there but might not be as safe after a few runs.

 

I would also suggest "adding lightness."

If you can get under 5800#, you'd be a good .6 faster, I'd reckon.

 

really just have the head magnafluxed for cracks, and have it check to make sure its flat, so the orings and new headgasket seal good, but 60lb valve springs, you could do titanium reatainers and keepers but they aren't necessary, just like you don't need a cam, but it would a nice extra if you did have the extra coin for it. just make sure you don't go with a turbo thats too small. if its too big theres lots of ways to fix that.

 

sweet thanks alot for the info!!!!! is there a cheap way to upgrade to twins by the way???

 

yes by a nice turbo from htt like this one http://dominatordiesel.com/catalog/p...if42l3pc63c817 then when your ready just buy all the piping and bottom turbo...thats my plan anyways and that turbo in the link is pretty decent size, so then when you buy a bottom turbo and have twins you don't have some wimpy twins that can only push 600hp, you have a nice set of twins that is capable of over 700hp thats what i would do if i were you. and what i hear rip at source automotive is the man to buy parts for twins from.

 

so whos the best shop especially in salt lake utah... or someone close to me and what kinda prices...

 

so my head is at the shop im anxious for it to be done bad!!!! still haven't decided on what turbo im doing any info??? i don't wanna do twins so i need advice on what turbo to run......
