243 Heads
#11
What do you mean by "am i running any gear" i had talked to you a while back about heads, on LS1Truck, but just haven't really gotten around to them because life has been busy, but i think i'm ready to give it another go around haha...

"gears" differential ring & pinion....I may be wrong since i don't know alot about how a 5 speed truck runs through the 1/4 mile... but i would think a set of 3:73 would help your times...but again im not sure what a 5 speed truck comes stock with...you may even could run 4:10's..my truck came with 3:23's

Cool.... i appreciate all the help, too i just talked to a guy on the phone, and he said, that since i eventually want to put a 6.0 in my truck, that i should just have the stock heads worked on, and he could get some pretty good horsepower out of them...Its not woth the money of buying the 243's, then get valve work done on them.... So i think i'm just going to stick with my stock heads.

All the new trucks 07+ come with the 243 heads. My 07 4.8 has them and runs great with them. But like TXSilverado said, they're probably not worth more than 15-20 HP. I'm pretty sure thats where the new trucks are picking up the extra 15-20 HP in stock form.
