Looking for all of the above.

I have a 2005 6.0 LQ4, looking to put 243 heads in it. Would prefer that they are ported and polished but for the right price i would consider stock heads. Preferred unmilled too.

Also looking for a good cam setup to go with it. Thinkin around 228 or 230 would be good.

Last, looking for a 300 stall converter for a 2000 4l80e.

Otherwise point me in a good direction where i can find them cheap. And yes I have tried LS1 tech. Heads are the first thing i would like to purchase though, then i will decide on the cam
