Every single week I have someone calling, texting, or messaging me about a set of LS heads they have, wondering if they will work for the 700-800 horsepower combo they want to build. Every once in a while I have someone ask which one will make real power, meaning more than 1,000. Or worse yet, I have someone hitting me up asking if I have any of the above lying around. My answer to the first question is always that their heads will be work just fine. Of course this always leads to more questions and me ultimately giving them turbo advice.
That advice is to save whatever funds you would have spent finding the heads you don’t have but think you need, and instead using that money to buy the best turbo you can afford that is capable of making 20% more power than you want. Spend some money on a good intercooler, which does NOT always mean expensive FYI, and go after it.
My favorite though is when the “Do you have any XXX heads sitting around?” question comes out and I say “I don’t know.” Cause I don’t. I know I have a couple sets of LS heads sitting in the garage, but could NOT tell you for certain which ones they are. I think one set might be 862 but I can’t be sure. I’d actually have to look. Regardless of which ones they are, I would absolutely not care if I was trying to build an 800 horsepower boosted LS combo for a street car.
Want proof I’m right? From the guy that taught these facts to me? Watch the latest from Richard Holdener.
