At the beginning of any complete engine build-up, the block needs to be cleaned. To do that, all of the block's plugs must be removed (even with a new engine) to allow cleaning access to areas that enable oil or coolant to flow. LC Engineering only uses American made brass freeze plugs. They may cost a little more, but they won't weep like the zinc coated ones, and brass will never rust, so they live longer.
Any true engine builder knows that the brass plugs are the ones to use no matter what the application. Any antifreeze leaking from the engine will be in the path of the rear wheels and could cause a lack of traction and cause the loss of a race. All because of a low dollar part. Build with confidence no matter what you are doing. These American made freeze plugs are the only ones to use.
NOTE: 2RZ will only use one of the 40mm you will have two left over.
