First time replacing heads and weird gasket issue.

Oh that’s awesome! Thank you so much for that. The vid seals the deal for me, ha ha. I simply could not understand how it could have been wrong when the dowels on the block lined up. Flipping them over would make the dowel location on the gasket all wrong.

I can go to sleep happy now. :D
You just gotta remember the orientation if you have the block decked, they toss the dowel pins, and you don't have any to replace them!
