The HKS gasket is an MLS gasket. MLS gaskets are a lot less forgiving than Composite gaskets when it comes to sealing. If there is even a slight warp in the block or the head it's not going seal because they don't compress and spread out like a composite gasket does. MLS gaskets also require a lower roughness (RA value) to help them seal the head and block surfaces so that is another reason for needing the machine work.

I'm not sure how much boost your running but if you are just driving on the street and won;t be running over 25-30 psi I would just use a Felpro. Others may say go OEM but I'd save yourself the 250 bucks on the HKS gasket itself and the cost of the machine work.

ok thank you. i do plan on making as much power as the car lets me on a 62mm turbo.

A regular felpro composite with regular arp's is fine to low 30s on boost, with L19 studs mid to high 30s with good tune. For 40+ safely you will need a MLS or O rings with composite.

ill need to look into these L19 studs i was just about to order a set of arp head studs

What are your goals? The regular ARPS are quite good and about half the price of the L19's.

long term goal is to push the stock block as hard as i can
