I just put together a 413 max wedge engine for a friend and have a question on rocker arms. It had a set of Harland Sharp rockers with the engine when he got it. I put them on, but what sucks is they are bulky, compared to stock rockers. The valve covers wont go on or off with the intake installed. Is there another brand rocker that will work and give enough clearance to get the valve covers on and off. I dont mind switching to a stock rocker they are just a little hard to find a good set. Anyone know where i can get a stock set or another solution.

the left valve cover with go on by spinning the crank and a little pressure on the cover. The right side go close so I popped it a few times with the palm of my hand but it will definetly be a job to get back off. I think the Isky or Crane either one would work fine but Ive never seen them for a Max wedge.

Just for fun try slowly turning the crank and see if there is a spot where the rockers are positioned such that the covers can be wiggled off and on. If there is then mark the dampener for future reference and repeat on the other side.

I guess I should ask the dumb question, do the max wedges use an offset intake rocker because of the larger intake port ?

All the OEM stamp steel max wedge valve covers I've seen are not like the non Max wedge covers for the B and RB motors. they are a little bit taller and maybe a tiny bit narrower across the tops also. No clearance issue inside with adjustable rocker arms, unlike the stock steel valve covers with the stock stamp steel rocker arms and shafts
My original 1963 415 HP M.W. car had 4 bolt valve covers that had the tab on both ends on the spark plug side for the added 2 extra valve cover bolt holes that Mopar added in 1964

Any combination of parts that isn’t: factory iron heads, factory intake, factory valve covers…….will create(or solve) its own set of problems.

I dyno tested a 426mw based stroker FAST engine years ago.
Stock 286 heads, stock intake, stock 1963 valve covers.
The engine had a .680 lift cam and used HS rockers.
The VC’s could be removed, but it was a wrestling match……..and the crank/cam had to be at the correct angle to get them off(different position for each side).
The engine builder had worked out the positioning during assembly and had marked the damper accordingly.

I’ve also tested an engine with the stock x-ram, but using 440-1 heads.
.650 lift cam, HS rockers.
The raised port heads moves the intake father away from the VC.
Much easier to get them off on that combo.

The HS rockers are pretty chunky, and do add to the misery index.
“If it were me”, I’d make the swap to some Comp Ultra-Pros.
They’ll require a pushrod change.

I’ll add this……..
I’ve had a few sets of the repro MW heads here, the ones with the cast in stands, where the stands located the shaft farther from the valve than they should be.
Rockers would contact the inside of the valve tip.
I’ve had three sets here like that.
I’m not sure exactly if/how that may impact the VC removal situation, but I can see where it could have some kind of affect.
Might be better, might be worse.
