Well I got my factory 84 mustang valve covers powercoated all nice...and guess what...they dont' clear my roller rockers....well i had just the solution, make my own valve covers
Here is my steps and progress of making them (i'm still making them)
First thing I did was to get a set of stock 87-93 mustang valve covers and cut the tops off of them.
Check out the first image to see what we did.
Next I make some stand offs, they are made out of 6061 aluminum and the are 4 inches long. I had to do the following to them:
Center drilled them
Faced both sides so they look nice plus they are of equal lengths
All I have left to do on the standoffs is turn them down and then drill the hole through them.
Also I put the valve cover flanges in a bridgeport and shave them down so they are nice and level
The second image shows what we have so far.
