I think it's been proven on mine and SD's car we both have the mildest JWT cams his is 256 and mine is 260 duration we both have DLC coated buckets.
On my way to the shop with the headers.
You got me interested in those valve bucket the first time you mentioned them, how much did you get them for?
By the way, I found these in my email and thought you'd be interested to see the difference in the SGM and PPE layout.

Dare I ask......wats "dlc" coated buckets?? Also I've been asking others around if I should change lifters and was told no need.....glad u mention this to me first.
So here's another one.....wen I look up like on import parts pro they have Supertech valve stems +1mm or +.8mm.....how do I know which one I need?? And where do I find the hr valve stems.....they fit without any modification??

No problem on the link I hope it explained things. They use that coating in NASCAR. Waiting on my mechanic to get back to me on that part#.
Headers are installed just getting the O2 sensors extended should be dynoed in the next hr or so.

It is right before the long straight section leading to the merge collector.
Did you get a baseline dyno before the header got installed at RTtuning to see how well the car did with just the cams?

It's better to get the stock HR bucket for our cars since that one has the DLC coating. A lot of stock parts from the HR are nice upgrades to the DE. Like the studs, head gaskets, coolant piping, etc...
