just use a group a reinz gasket & a set of genuine headbolts.
my 4x4 running 26 psi has had 1 on for the last 4 years & i've done 3 track days & loads of 1/4 mile days since I've had the car in the last 14 months with no problems.
as above though if u use a metal head gasket both the head & block need to be perfeclty flat which will probably mean a engine out & full strip down as the block will have to be machined as well as the head.
