| rockers for track heat heads?
Hey so I got a super deal on some trick flow heads a while back from my friend but he kept his roller rockers, so i was wondering what I should get. I've got trickflow 185 heads with the track heat valve springs rated for 7k rpm. I also have 3/8 and 7/16 mounts. I was looking in the $160-$200 range. Any suggestions? I don't want any fragile Chinese eBay parts.

I have scorpion 1.72 on my trickflow 170s. They are really nice, but a little pricey.but they are lifetime warranty. If one ever fails they will send you a new one no questions asked. They also maybe a little overkill. They can handle 900 lbs of spring pressure.

They make the same rocker in 1.6
Just look how beefy they are.

you have to get whatever size studs you have. i think mine are 3/8 but i only have the 170 heads. so i dont know what size yours are. and you also have to make sure they are for the right pushrod. which mine are 5/16. so in my case i have 3/8 1.72 rr for 5 1/6 pushrod. if you dont kow for sure go to the trickflow website and look up your heads and it will tell you what sizes everything are.

They won't be tapped for both sizes and if you have pedestal mounts you will have to get rockers for them.
