I was changing my lifters yesterday and when I pulled the manifold off I saw that there were two small ports at the very back of the heads that were blocked off on each side , one of them fell off and I was wondering what those ports are for and what would happen if I left them open . Thanks guys

 

You're going to need to be a little more specific. Are you talking about the coolant passages and by blocked off are you refering to the stock intake gasket with the pinhole in it?

 

Yes I believe that it is the coolant passages, and I am not sure if its a part of the gasket because they shredded when I pulled the manifold off the blocks were just sitting there when the gaskets were off , but it looks like it could be apart of the gasket

 

Theyre gold colored right? Well anywayz I cant help u cuz I changed my heads when i ripped my manifold off but im just tryin 2 clear up what it is ur talking about.

 

They are the coolant passages and you can leave them open. It won't hurt anything.

 

Awesome , Thanks guys I appreciate you Help!:rockon:
