2-piece BBC valve covers?

[Michael]

Short-style valve covers won’t clear the Comp Magnum roller rockers on my BBC, but conventional tall-style valve covers can not be used because their installation or removal would be impeded by the proximity of the “Monte Carlo†bars (diagonals from the front strut towers passing through the firewall and connecting at the dash bar). In other words, those bars pass too closely to the engine, and that makes the choice of valvecovers problematic. Tall valve covers would physically rest in place without interference - they just couldn't be routed over the rockers and under the Monte Carlo bars.

 

Hopefully that wasn’t a too verbose explanation for a pretty simple problem.

 

Anyway, other than custom-machined valve covers, which I am becoming inclined to attempt, the only solution seems to be 2-piece valve covers. These are available for marine engines, for example here:

But those cost around $400!

 

Does anyone have leads on “reasonably priced†(< $150) two-piece valve covers for the Mark IV big block Chevy?

Would the 1.150" spacers that the speed shops sell help any? Found these on Summit.

 

 

Don't know if these are for Mark IV as i'm not up on my BBC models. There only $107. Seems high to me but better than $400 for a pair of covers. Sorry for only the pic but i couldn't link to the ad.
