Hey All...
As title says, i need info on head gaskets on Rb25's...
I'm looking to produce between 250-280 rwkws, but i'm unsure if i have to change the head gasket?
Some people say it's fine and you don't need to crack the head open, but i want a reliable 25.
If i do need to change gaskets... what type of gasket should i be looking for? what thickness, without loosing too much compression and driveability?
Help is muchly appreciated
