1.7 rockers with 380HP Cam

I’m not positive on this, but IIRC, the Hughes engines have a trick retainer they found to use on Magnum heads that allow that lift.

Edit, went hunting for you between period 2/3 of the Stanley Cup.
(Tampa is getting hammered.)
The description at the BOTTOM of the page says .550 lift.
Up top it said .620 coil bind.
