Hey guys, I am putting new cast aluminum valvecovers that are tall on my new motor. They came with no holes for breathers/pcv valves. Can you tell me how you guys did yours and maybe some pics of where you put them.

Be sure to put them between rockers not over them
Baffle them or epoxy a piece of aluminium on three sides under the hole
Don't forget to put a hole in for oil too ;)
Here is the last one I did
It is for a remote breather but you get the idea, these come with no holes too
The one in the front is a 1" AN cap so you can put oil in the engine & the rear is a -12 for a line to a remote breather canister that we use.
