So I have a 2010 GMC Sierra RCSB with the 5.3 and a D1SC procharger that ended up breaking a piston late last year. I finally ordered a new engine last month which was a 370 from Texas Speed and I was wondering what heads should I use for my application. I plan on leaving it N/A for a while til I can pay off some of the debt and have some room for potentially buying a new transmission once I add the procharger back in the mix. I have the original 799 heads off the 5.3 and an LQ4 with the 317 heads in my shed from another failed project that I could use as well. I wasn't planning on changing the heads once I add the procharger so I am guessing the 317 heads are probably the better choice but I wanted some outside input as well.

Was also planning on using the LS7 lifters but I have seen some mixed reviews on them. Wanted to see if they are a good choice.

And lastly any suggestions on rockers? I'm not sure if I should bother with the stock ones still or if it's worth upgrading them


Thanks in advance for any input or help!
