Hi, so my 1G 6 bolt 4g63 block is getting built. The machine shop had to take 0.010" off the block deck, it wasn't in the greatest condition obviously. I have a rebuilt 2G head with SS stock sized valves to go with it, it has had a minimal amount of material removed from its deck, a few thou at best if my memory serves me well. Both are freshly machined and I was planning on using a Cometic MLS HG.
I have all new front case, timing belt, and oiling components for the block.
I'm assuming degree'ing my cams and a piston to valve measurement is needed. Does anyone have any recommendations that might be commonly overlooked when taking a significant amount of material off the block deck? I hate to overthink it, I'm sure this has been done many times before and this isn't rocket science. I did some research but most everything online is SB Chevy or Ford stuff,not sure how much it relates to a 4g. I am working with my engine builder on this, but am always curious about other's opinions as well, plus I prefer to sound as if I have somewhat of a clue when we converse. Any help is appreciated.
I am thinking a thicker head gasket is probably required, not sure about this yet. Makes sense that if 10+ thou is taken off the decks, a 10+ thou thicker HG should bring things back into spec, is it that simple? I will be running fairly high compression Wiseco HD e85 10.5-1 pistons, with Carillo steel rods.
Thanks for reading,
Bryan
