Need help taking the h/c plunge.
Well, I am lost. Something bad is wrong with my engine right now. Some of you guys have suggested that one of my oil control rings are bad. I have oil in the air filter, maf, intake, and blowing out the exhaust coating my o2's. I think I screwed up a valve. I broke off two header bolts when I put in my LT's, and my problem started shortly after that install. I am to the point where I am going to tear down the heads, (check the rings while I am in there) then do some head work, and put a cam in while I have it tore apart. I have a goal of 450 rwhp. I am thinking that I am better off scrapping my 241's and picking up a set of 243's. Since I am going to have to have work done, I think it would be better to do the work on better heads, right? I def dont have the cash to get nice heads from the big guys. So, can I pick up any 243 or 799 head used? Then, what do I have to have done to them? I know a good machine shop here in town. That is about all I know. Do I need to replace everything in the heads? Do I need to have them ported to achieve my goal? I can follow the cam install write up no sweat. ANd I am thinking I am going to go with the 228r cam. Will that get me to my goal? I am not looking for an ET, just street warrior. My car is a M6. So, if someone would be kind enough to hold my hand and walk me through this, I would appreciate it. Also, this is not my DD. And I do have to get it past emissions. Just a plug in test here, so a tune from Frost should do the trick. (I only got to put 1 k on the first tune.) (--- sucks

What's your budget? You can pick up a H/C package from TSP with worked over 243's for around $1900.

I saw those. Can't I do it for a lot less than that?

Keep in mind that the package from TSP comes with your choice of Oil pump, LS2 Chain, Valve springs, as well and all other necessary parts brand new when doing a Head/Cam swap

So, that package is literally everything I need except the tune?

If it comes with the cam, heads (gasket), oil pump, valve springs, timing chain, and hardened push rods....I would say yes.

+1 on going with a h/c package. You will probably have over 1k in the heads alone by the time you buy a good used set, have the machine work done and add in the new parts. Reaching 450rwhp with a stock cube ls1 is going to be tough on a budget. You will need a big cam, good tune and a fast intake/tb set up to get close to that. 400rwhp is more realistic especially if you are on a budget. I'm sure if you call TSP or other reputable retailers they can help you pick the right parts to get close to your goal. Don't get stuck on numbers it's how the car drives that is most important.

With my entire build I have about $2600 - $2700 into it with me doing the work. That's with 2.5 ls6 heads milled .020, Torquer v3, injectors, lifters, oil pump, timing chain, gaskets, UD pulley. That does not include a tune. Then you'll probably need a upgraded clutch if you already don't. That combo should get you in the 430-440 rwhp range pretty easy, maybe a tick more with a lightweight flywheel.
The heads are assembled and it comes with push rods but an oil pump and timing chain are extra.

Okay, I did some research and found out that my problem was the pcv system. I replaced the whole shit pot and then replaced the O2 sensors, cleaned MAF, plugs, and she passed emissions. So, I am good for two more years. I have a catch can sitting in the garage, to eliminate the problem. I just want to let you guys know that i am not going to wait two years to get H/C package. I appreciate all your advice, and I am sure I will need more as I go. Looks like PRC Stage 2.5 heads, and pick a cam. Hopefully by fall.
