I have a standard bottom end and a race spec port and polished head what head gasket should I use athena or stock I want to push about 1.2 bar and 250bhp

Also should I use standard head bolts or arp

First most important thing is check piston and head inlet valve squishing area cap, there starts Your head gasket calculation, detonation will kill engine very easily and piston ring are first place were it starts. Max 1mm and under is way to go...

Go for an standard head gasket and head bolts mate if you go for a MLS Athena gasket your block will need decking

So if I push 1.2 I would be playing with fire? What size thickness is the standard head gasket? What boost and hp will standard bolts hold

the stock h/gasket and stock h/bolts will handle the power and boost you mentioned above without issue----assuming you have oem/genuine items and your engine is in good condition


some people have pushed the stock h/gasket and h/bolts far beyond your goals...300++bhp, 1.5/1.7bar




you will need a good tune regardless
