OK SO!

I am building a LS Vtec and my headgasket came in the other day... it says right on there 81mm... now im having the block bored .020 over to 81.5mm

should i have a 82mm headgasket or is the 81? I thought if you had 81.5 you were supposed to go the bigger size?

Help?

NOW POST **** NOOB OR THE HMT GODS WILL KILL YOU

 

im pretty sure you can run up to + 1mm with stock bore gasket, I have run 81mm headgaskets with 81.5mm bores on my old ls

 

cosmetic head gaskets are just for looks. run without it and cut your losses

 

head gaskets aren't needed if your block and head surfaces are true. just a layer of copper spray
