I saw on the FB page today for the grey motor enthusiasts that yells Terra have released a bolt in Roller Rocker kit for the grey motor.

Apparently no mods or grinding required to give 1.65 valve lift - pretty pricey at 1760$ including but might be a worthwhile mod for the go getters out there.

$1760

yeh they are not cheap but for someone doing a head rebuild that might not turn out to be much more than doing a normal lifters and springs job anyway and being a bolt in kit might actually save the engine builder some time and you $.

I already know a few people who will get them.

If your rockers/shafts etc are worn it's more valuable, but like all grey parts every little bit helps and you don't "really" do up a grey to get 300hp, you do it because it's cool and you can.

I'll certainly be looking at them when Top Torque do my re-build - as you say GreyEJ if my stock set up is on the way out it will need to be replaced anyway so that will save a fair bit off the cost of the yella set up and if it lets the Grey rev a bit smoother then it's gotta be good - pair it with twin stroms / mild cam and electronic ignition(petronics style) and it should be a great improvement.

Sorry mods - just realised there is another thread already started on this - pls feel free to remove this one.
