I had the Holley Tall Valve covers on the engine and in the car, but I ran into trouble when it came time to install the coils.  The stock coil bracket was no longer useable and the hole pattern from the pedestals on the new valve covers were different than my stock ones.

The whole reason for buying the Holley Tall Valve covers was because my Comp Cams 1.72 roller rockers were too tall for the stock valve covers.  Since I had to take the valve covers off, it was a good time to paint them.  I bought the cheapest option from Holley and I never really liked the way they looked.
After 3 coats of Chevy Orange and 3 coats of clear, I was ready to start on some custom brackets to get the coils to mount on the valve covers.  Apparently MSD makes some coils with the mounting holes 72 mm apart, but I had already dropped serious money in some genuine AC Delco replacements which had the mounting holes to fit the stock coil bracket.

So I had to drill larger holes in the mounting holes of the coils and I made my brackets out of a strip of $4 aluminum that I bought at Lowes, and slapped them on.  I think they look pretty good, all things considered.

Remove Alternator, Valve Covers, Rocker Arms, Push Rods GM Chevy Tahoe Vortec Engine LS vid 8

I’m happy to say that the removal of the alternator, valve covers, rocker arms, and push rods was very easy!  Everything went exactly as you would expect them to go.  My only exception was the dramatic difference in coloring of the rocker arms and valve springs from the passenger side to the driver’s side.  Passenger side was gold in color and (to me) looked healthy.

The driver’s side looked brown, burnt, and very unhealthy.  I posted a question on one of the Tahoe discussion boards, and never heard back from anyone.  So either, it was a stupid question, or no one knew the answer.  I still don’t know.

You will notice the careless way I threw all the push rods in the box.  I already purchased a cam, new springs (and hardware), new rocker arms, and new push rods, so I was not too concerned about where everything ended up.  I did keep the rockers in order, just in case something came up that I needed to identify what was what.  If you are planning a cam swap without replacing the push rods and rockers, take care in knowing exactly where everything came from.

By the way, you can’t pull the valve covers until you have removed the spark plug coil packs (check out Video 5).
