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. 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.

In theory, there is no difference between theory and practice. In practice, there is.

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

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. Good luck with that, at any given time rockers will be insimilar positions - its not like they'll all be open or closed at once !! I guess I should ask the dumb question, do the max wedges use an offset intake rocker because of the larger intake port ? There is no "intake" or "exhaust" rocker, there is only left or right. What is intake on one cylinder is exhaust on the next. So, all rockers have the same offset. What allows them to be used on either or is the shaft "hold down". The narrow one's let those rockers move in closer to each other so they center on the exhaust valve tips. The wider ones push the rockers further apart to center on the intake valve tips. I think the Isky or Crane either one would work fine but Ive never seen them for a Max wedge Copies of the origial MW - either will work fine. As to the OP's issue, are you using studs or bolts to hold the valve covers? You would definitely have issues getting them off if using studs !!

Factory Max Wedge rocker arm offset is the same as all other big block rocker arms.

This DOES work with my stock covers, Sharpes, and a .650 lift. I do have to remove the alternator as it slides out the front. The hangup is either the number 6 or 4 rockers. Good luck.
I meant to say above that rotating the engine just right does work.

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.

Can you divulge the HP on the FAST engine? Or ball park
