Input on which roller rockers - BBC
I am starting to gather parts for the rebuilt. which roller rocker is "better" either FT or roller cam - but nothing radical - around 550ish lift.
scorpion endurance 1.7
or
comp cams, Ultra Pro Magnums
I like both and have been told by 2 different builders - 1 likes scorpion - 1 likes comp cams

I have had real good luck with the scorpion rockers in the past. In fact I have 2 sets of the "marine endurance" scorpions getting ready to go in my blower motors. I haven't used the ultra pro magnums, but I would think either of those rockers you are looking at would be more than sufficient for what you are doing.

I like a rocker arm with good geometry. I personally like the Crane Gold Rockers. I've found out of a comp cams, scorpion, and crane rocker, the crane had the most centered, and narrowest sweep pattern on the valve stem.
Heres a chart you may find interesting. Not all rockers are equal when it comes to ratio.

I've been running the crower stainless 1.80's for 8yrs.they had perfect setup on .620"+ lift cams.plus if they need to ever be rebuilt,its relatively cheap.

What do they cost to rebuild them? In the long run, they are probably worth the extra upfront cost.

I bought comps best ones years ago before switching to shaft rockers, the nuts were brittle junk and cracked in half EASY , switched to arp nuts and they worked fine. Crane gold or scorpions is what i use on everything that doesnt get shaft rockers
