Head and Cam help
I am going to be using an lq4 block and crank with better rods and pistons.. I am going to use the ls3\l92 heads. I found a set on summit for 600 http://www.summitracing.com/parts/na...FTRMMgodIFYA8A
and a set on ebay, but they are an off brand and seem a bit different, can anyone tell me which is better

I know you need to match valve springs to cams so I was wondering if these two will go together http://www.lingenfelter.com/mm5/merc...9#.U70_wvldWap

The intended use is in an extreme 4x4 with aprox. 44 inch tires. I want a nice fat mid range with a wide torque curve, but also decent hp. I am new to all of this and havn't started getting parts together yet, so if anything I stated was wrong please let me know.. I am trying to avoid making any costly mistakes (I know fat chance right lol) Thanks in advance for any useful input

You should go for the genuine GM LS3 heads as they have powdered metal valve guides which will withstand the side loading incurred by using stock rockers. The bronze guides in the ebay heads will wear rapidly when stock rockers.
The cam looks good, but a custom cam could yield more mid range torque.
The Comp 26925TI-kit would be better than the 921 kit in my opinion.
Please consider our dual spring kit also. http://www.briantooleyracing.com/660...ers-sk001.html

We offer several cams designed specifically for LS3 heads. Our Stage I cam is what I'd use in a heavier vehicle as that's what it was designed for. The specs are 221/228 .609"/.571" 112+2.
In back to back testing less exhaust lift make more torque everywhere, so that's why our cams are designed the way that they are.

Now to sound like an idiot, how would I know which length pushrods I need? I was under the impression you needed the cam and valve springs and all that installed to measure? Thanks for your patients

What I did was estimate such a range, then bought several different lengths around that number some shorter some longer. Then when I finally measured, I used the correct one and returned the rest.
