Thank you. The problem is i can barely get to the adapter recess in the block to remove the old gasket. The header takes up about all the working space. Didn’t plan on doing this Sh$@ on a new engine

I feel your pain my friend. Headers are nice BUT can be and are a pain in the a**. Wait until you have to remove your starter... grrrrr.
