LOL, no, it's not a 2.0 Cavalier head. It's an LT1 small block Chevy head. As I mention in the first post, the first two, clean parts, are new. The rest are 90k parts.
This should answer questions on the parts;

IMO, the 1.6 rockers are the best "bang for the buck" in rockers. They are as reliable and quiet as the stockers, and are only $74 shipped for a set, from Scoggin Dickey. Give the majority of the gains associated with 1.6 roller rockers.
The rubber piece, you mean the air pump hose? Well, I'm a maverick there. Giving the cats additional air makes them light off quicker, making them last longer. Just because you CAN remove the airpump, does not mean you SHOULD. IMO, GM took an easy way out on this score. They proved the cats would last
long enough, without the air pump, to satisfy the EPA. That does not mean they will last long enough
for me... Replace the check valves($20) every couple of years, and the air pump will last the life of the car. It costs no power, so I'll leave it... If it does break, I've got a couple of free spares. For some reason, people give them away.
A longer shot, after the parts were changed. Yes, my engine is dirty, I have better things to do with my time...
