Coolant transfer tubes

I am having a problem getting the plugs out of the head for the transfer tubes I had the engine rebuilt and heads were swapped the one that was on left is now on the right and vise versa, could I run the tubes in the front of the engine or do away with them. what are your suggestions??

Thanks CED

Don't do away with the tube and it needs to be on the back for it to be of any use.

i had problems sealing mine when i put afr heads on, didn't get new gaskets for them, so i just used some pipe fittings and hose to achieve the same thing, you need then and they need to be at the back.

Dont mean to infringe on the post but Im doing an engine swap and I was going to remove the coolant tubes on the back of the cylinder heads but it seems like they are necessary. What is the purpose for those tubes? What would happen if I delete them?

If you look at an intake for a gen 1 small block you'll notice that the intake has a passage way for coolant, which flows from head to head also the thermastat is located in the intake. when you look at an lt1's intake and head it only has the intake ports, no coolant.

the purpose of the tube is to avoid pockets of steam from forming which can cause hot spots in the head which can cause detonation and damage to the head. yes people run without them without problems but is it worth the risk over such a cheap piece? no!!!

Although you didn't ID the year of the engine, I assume it's a LT1. If I had this issue, I have a couple of options:

Swap the tubes from the front to the rear; which may be difficult especially on the passenger side. 15 mm six point box end wrench or socket, OR

Remove the heads and swap them.

You can fabrictate something that'll serve the purpose but, for me, that would be a last resort measure.

Just my thoughts.
