Yeah, but it certainly can't hurt.

I know that. I was saying that to basically say that motor oil should do the trick just fine.

I didnt have to pull the fuel lines off (as in lose fuel), I just un-clipped the fuel line mounts along the fire wall and sc. This gave me enough slack to pull the lines out of the way, still #6 cylinder valves were tough to get to, would have been easier with the throttle body and egr out of the way?

Thanks for the input guys.
I'm going to give it another go this evening without disconnecting the fuel lines.

I just heard back from Scott and he tells me that GM changed the design for 2004, and they tell us that the new black ones are superior to the previous orange ones. So I'm going to replace them.

I also did some inquisitive checking of component weights just for the groups knowledge.
The OEM pushrods are .065" wall thickness but larger outside diameter compared to the new INTENSE rods that are made of stronger material and .083" wall thickness but smaller outside diameter.

I took some parts to work and weighed them on a very accurate electronic scale.

The OEM rods weigh 48 gms. The INTENSE rods weigh in at 51 gms. A 6% increase in weight but by far stronger and the ends are not welded on balls that can be prone to breaking off. Definitely a quality product.

The OEM 1.6 rockers weigh 222. gms. The new 1.9 INTENSE rockers weigh 198. gms. An 11.% decrease in weight.

Yes, the new black gaskets are supposed to be better. Don't know how, but they are. I missed that you were asking about it earlier until I re-read it just now.

The OR pushrods are definately a quality product. If your not worried about the stock ones breaking then you definatley don't have to worry about the OR rods breaking, they are definately strong.

And overall you are actually losing 21gms. in the valvetrain. So you have a lighter, yet stronger valvetrain, and you have more lift. Its much more efficient now, and should be much better for revving. Should take revs up to 6500 like a breeze. My dad has turned the GTP to ~6550 before at WOT in 2nd gear (on accident, forgot to put the shiter in D) and it took it with no problems at all. This is with 85lb. springs, steel modded retainers, OR pushrods, and steel 1.9 rockers (non-rollers), stock valve seals. So, your valvetrain should be pretty stout, since its lighter than his is, and its roller.

Well I got all the valve springs done tonight. I took my time since it was the first time I have ever done them with the head on the car. It was a breeze.
Definitely helped to have a magnetic pen to lift out the spring retainers. :P



The backside was done first. I didn't have to remove the fuel lines or wiring harness, just pull it back a little.



Pic of backside with new springs and Titanium retainers. No need to weigh those retainers....they are pounds lighter than stock.



Pic above of #1 cylinder with the new springs compared to #3 & #5 with stock.



Above see how much taller the new springs are than stock.

I'm off work now until Jan.3 so I can pick away on finishing up the rockers.
More pics to come.........
