Tall valve covers with A/C
 

Hi guys, I am looking to build a stroker BBO from Rocket Racing Products for my '76 Olds 442.
First, do you recommend these guys? The engine is for street and strip and cruising in my Olds.
Second, do tall valve covers fit with the A/C blower in my car? Any modifications should be made to the A/C?
Again the car is a 1976 Olds 442 with A/C that is a luxury I am not willing to spare. So any recommendations on the build are welcome.
Thanks,
Bassem
