I don't think the stock rockers are bad at all. Have you seen what they look like?

There have been multiple rockers failing ... including on a completely stock motor.

We modify the rockers on all our in house builds. Unfortunately they can only be done in house with our complete head packages.

I was unaware of this. I'll have to do a search. Thanks for the info.

Another vendor made a post today that indicates the 14's have longer valves than the 13's. Any idea why Subaru would make this change?

+1 , few months away form company yearly bonus time. Going to be mostly financially irresponsible and buy car parts

@FullBlown +1 for flow numbers at stockish lift levels. You guys got awfully quiet once the questions started flying

Those gains are really impressive at .500, but if you want people to throw their money at you then we need to know what we should expect without massive cams.

Also, how are the rocker arms holding up? I've read that these can be one of the weak points of the head on the FA20...
