Why are you bore it that much ?
My friend has a lot of miles on his block and I'm expecting the cylinder distortion to be awful and I am expecting some nice marks in his cylinders.
I dont know if it will have to go that big but just in case.. I wanted to know if the stock gasket would accept that kind of bore 3.78". The bore on the gasket is not completely round and I am assuming that when the gasket is compressed that some material may enter the combustion chamber. I was told that some material would be ok as long as the fire ring is sitting on the block and the guys at RCD said the head was a closed chamber design so the some material will be ok also.
What do you guys think? Like I was saying it might not have to go that big but I would like to do my research just in case.
