i'm almost done putting together a 6.2 for my truck but before the 5.3 gets pulled out i kinda want to push it further to see how it runs. I have a nitrous system i wanna run with a 100 shot. On top of that i would like to install the ls6 cam i have put away along with the yellow springs, some rocker arms, and the tbs intake. I dont plan on spending much cause i have had these parts just there and wanna put them to use. my question is though. recently i noticed i have a broken bolt on the back of the head where the header bolts on. since i'm gonna have to pull the head off i was thinking of getting some head work done. but i know nothing about it!? Where do i start and what do yall recommend? also for those running a similiar set up what do yall run in the 1/4? just out of curiousity.

The head bolt is a regular issue on the 5.3. Did it break the driver side last one in back? Heads usually port & polish or bigger valves with heavier duty springs, depending on cam. I did a good bit of work on my engine and I ran a best 13.686 1/4 mile

yes sir driver side far back. Work you did on the engine was similiar to what i'm looking to do? or was it with what you have in your sig. also im asking how much to get them ported i have no idea wat the numbers mean. first time in this area

I just went ahead and got a set of heads pre assembled & cam that Patriot offered, the intake valve is 2.02" and the exhaust is 1.57". The truck is extended cab short bed when I started it ran between 16.25 -16.50 seconds in the quarter mile now it's between 13.68 -13.75 at around 98 mph. My 2010 Camaro with the L99 and auto trans runs 13.74 at around 102 -103 mph stock.

You should run a bigger shot, like 200. And see how she runs
