I have ran harland sharp rockers for years on both gen. v & vI with no problems. I have ran EMI alum. covers on the last motors, But I did run tall moroso on another, But with EMI headers.

Those are the studs I bought.

Griff, did you install 1.7 or 1.8 ratio rockers or your 454Mag?
Did you notice any extra power?

Hey Jayhawk,
You go first, it's still too cold in these parts to work on the boat.

I've gotta do the steering first. I'm probably going to order the rockers this week. It looks like just getting to them will require exhaust removal. I don't know that I'm feeling that sporty this early! I guess we'll see

I used the Summit brand roller rockers in a 1.7 ratio. I upgraded the cam and needed them for clearance.

BTW, the Crane Gold's no longer need to have the corners ground off. They changed the desogn a little.

Jayhawk,
I have a set of Harland Sharp rockers 8 1.7 and 8 1.8 ratios I used for less than 1 hour. I added them while the boat was in the water trying to get more lift on the intake side. I got nervous and did not want to risk coil bind because I was at the limit for the springs. This year I just changed cams and springs to get the extra lift. And bought a complete set of 1.7.
So if you are interested before I put them on Ebay PM me.

this is a pick of the cast valve covers from Steff's/B&B Perf..like a lot of the rest mafg's it has the angle for clearence for the headers.It has about 1/4 inch clearence,so its real close.

I dont think the Moroso sheetmetal ones will work
