Hughes Roller Rockers

[splicer]

Anyone here have experience with Hughes shaft mounted roller rockers ? I've been running Comp pro magnums without any issues but Comp doesn't make them in 1.6 ratio and I'd like to try that on the Indy heads I'm installing this winter.

Thanks

I have a set of 1.6 that I put on 2 summers ago. Mostly driven on the street, but made about 15 or 16 runs on the track with them. They seem fine, no problems at all with them.

I have the 1.6 rockers on a Hughes solid flat tappet 618/626 lift and 258/[email protected]. The engine was built in 2007 and no trouble with rockers.

Me too. Hughes 1.6 rockers on stroked 383/426 engine built in 2007. No problems whatsoever so far with about 1000 street miles driven per year on it.

Cam is hydraulic flat tappet, .539/.558 lift, Duration at .050" is 223/228
Hughes #1105 springs, 130# on seat, 300# at .500" lift. Installed height of 1.830"

Pretty mild cam, but it was already purchased new and supplied with the project when I bought it, so I went ahead and used it.
