Re: patriot heads package

Check the back of the T/B blade for oil it could be your PCV system thats causing it. My car would burn a quart of oil every 200 miles when I put my cam in and that was the cause. Smoked like freight train it never stoped idle decel alwas smoked. After I put a catch can on it. It went a way.

usually cnc ports are very big to make room for the cutter

The intake runner on the patriot head is 213 cc.I do not totally agree with cnc heads are big to make room for the cutter.There is no difference in our cnc head vs a hand ported head in the roof area.

Any clue as to why my car would go from having no oil consumption issues (I was a lucky one) to having a massive oil consumption issue after the installation of heads/cam package, as well as what would cause my plugs to have a large amount of oil on them???

Possible piston ring blow by from higher pressures and higher RPMs. Does it smoke under WOT, idle, shifting,or startup? Usually smoke at WOT is rings. If it is between shifts , at idle or at startup, that is usually valve seals.

No smoke at WOT, but 1 out of every 2 times on startup there is smoke. Doesn't matter now because the engine is being pulled later on this week and having the bottom end rebuild due to a spun rod bearing.

After I have the engine pulled I will have the shop take off the heads and inspect them to see if the heads are the culprit. If they are, I will let you all know. Thanks.

I've danced around this subject more than once, but here's the blanket statement:

If you are paying more than $1600 for a set of Stage 2 CNC heads FROM ANYBODY, you're getting raped - and I don't care whose name is on them.

21st Century Muscle Cars in Dallas, is charging me $2,795 for their LPE CNC ported, polished, and paper-rolled 2003 LS6 heads, installed. Is this a good price or not??

I'd go with just the CNC work on the heads if you are going with LPE. The paper rolling on those heads is only worth about 6 CFM. Thats about $100 per CFM, as my understanding was they charge about $600 to do the paper rolling and smoothing.
