we used a felpro and arp head bolts ,just make sure you use the 1800 cvh cam belt and tensioner too as the 1600 will be to tight i cant remember what the torque settings are as it says the correct ammount with the head gasket or non stretch arp bolts ,i think the cometic gasgets are good to if a bit pricey ,for the ultimate you could go for a copper gasget aka farriday engineering( spelling lol) really depends on what boost or spec and how much
cheers
