Looking for Valve covers for my new engine and there seem to be lots of choices. But they are expensive, and I only want to buy them once!

Running a 10.4" deck Hemi with the old "433" dual plug heads (only using one plug) and INDY rockers. I have a set of the old steel dual plug valve covers, but they are mangled on the exhaust side for rocker/ spring clearance. Which aftermarket valve covers should I be looking for? On one of the old thread searches I found someone said that the INDY valve covers did not clear the INDY rockers.....figures....

This is going in my 68 Barracuda and I will need to be able to pull them often for valve adjustments.

I saw some of the fabricated types like Mancini sells, but they use the long bolts and I worry that may make the already tough task of pulling the passenger side cover off even worse. The Barton and Stage 5 covers look like they may work, but they are costly and I don't want to spend the money and then hope they will fit.

What do you recommend?
