So the rear differential is new, does that mean that there was a problem and it was fixed or does that mean that it was upgraded from 4.10 to 4.56 gears to match the tires? The reason I ask is because if you re-gear the rear and not the front then you can have some serious issues when the 4x4 is engaged.
My understanding is that double roller timing gears and chains are less likely to stretch than the stock style. When I replaced mine I went with one like the stock chain. It was tighter than the original but I didn't notice any change in how the truck ran or mileage.
I'm surprised the original owner got the heads replaced and didn't have the plenum gasket changed since it was already out.
I've heard that an off road y-pipe makes a huge difference in power for around $100. It might be an issue for a California truck though.

I believe the plenum gasket went after all of that work. When I bought the truck it had a clogged cat, probably due to the plenum gasket, and I think she was fed up with spending money on the truck. For her to let it go at 3600 is testament to her not wanting to deal with anymore cause as it stands now, the blue book is 7k.
Just noticed this morning when I got to work that the timing cover is leaking oil and coolant.... YAY!!! <- sarcasm. Looks like Ill be doing the timing chain a lot sooner than anticipated.
About the y pipe, Im not too concerned with emmisions as I can always swap back to stock when needed.

They were most likely added when the heads were changed out.

Got the SCT tuner today from HF. Holy hell, running the 91 octane program, with 91 octane fuel of course, and the truck is a completely different machine. Accidentally spun the tires when I took off from the light. Didn't really expect that at all. Really need to change the spark plugs and get my timing chain done now.
