Is it nessecary to have the crossover from head to head? Or can I put the blockoffs on the front and rear of the heads? Ive been searching and searching and cant find the answer. Also, anyone have the part number for the block offs? or so they come complete in the coolant crossover kit?

 

nevermind found the answer....

 

Why would you want to block them off? They are there for a reason.

 

yeah i realize that now, didnt know what purpose they served.... now i need the part number for an extra crossover pipe to run in the back of the heads
