But the dry sump pumps pull 20-22 inVac in the Crankcase , You cant even pull the damn things off with no bolts in them when the engine is running !
Im sure someone makes a good BBC 2 Piece cover , but the are gonna be pricey!
Been awhile but i remember somewhere around 500 dollars for the set and i think i had to buy screw in breathers also. I have KE headers for 7 plus years and not a single problem so i'm 50-50 with this goof.

I had to add the breathers and puke tanks and they still leaked like a sieve.
