For those that demand the very best , I had the pleasure to test the new prototype "needle bearing" , 1.3 ratio rollers from Gage Motor Sports . And compared to their current Rockers, these did perform consistently better . Is 1.6 possible now ? Nice job Max. I believe production is a few weeks away and they will B available for the GX390 Big blocks . I think these might get "lost in the mail" LOL . "Black Venom" . The Bar just got raised .
 
Hey guys , I am new to this Fourm and I'm not trying to get my head bitten off but if someone could help me out it would be muchly appreciated. I'm building up a gx 390 (ut1) and it's getting close to being finished ! But what roller rockers would be appropriate for a 356 welded lobe cam , I'm running 60lb valve springs , arc piston , arc con rod , bull frog motor sports big valve head milled .80 tho ( ported and polished) . If someone could chime in it would be great . I've got tons of money and time into this build and don't need and issues .

The rockers listed by the OP would be a good choice. Be sure to check for clearance issues (valve to head and coil bind) if you go with 1.3 to 1 ratio. Your going to have .463 lift at the valve. The 1.2s should be checked as well for that matter. I listed some links below of rocker choices. I couldn't find a suitable link for the Champion shaft rockers. They are OK too. I have not used all I listed. Raceseng made some nice rockers but no longer in production. I have seen some "Eagle" roller rockers on 390s before. Might be Harley rockers retrofitted? IDK. Also the use of most roller rockers require the use of a valve cover spacer or an aftermarket aluminum valve cover. Some get by with just removing the baffle but its close. Good luck.

I know this post is ancient but could anyone elaborate on the Eagle roller rockers fitted on the gx390 as stated in the post above? I have not seen or heard of this elsewhere and if possible I would love to see a photo of them fitted and part numbers as well. Thanks
