hi guys
i recently looked into ordering a metal head gasket for my KA-T build. i am thinking of ordering this exact kind its a Cometic Multi layer steel head gasket.
heres the link to a pick and some stats:
> **[Cometic Metal Head Gasket KA24DE 89mm x .040"](https://frsport.com/Cometic-Multi-Layer-Steel-Head-Gasket-KA24DE-240SX-S13-S14-1991-98_p_3133.html)**

> Part No. H1836SP5040S SKU: 3133 | Cometic H1836SP5040S Metal Head Gasket KA24DE 89mm x .040" Viton-coated outer layers Different bore sizes available | Price: 81.73
My question is how thick should i get it? i am going KA-T remember and i know that a thicker head gasket will decress the compression a little bit, but how thick should it be? the size i am looking at is 0.040 inches is that thick enough?

has anyone had experience with these gaskets? if so which thickness should i go? i heard that you should stay as close to o.e.m thickness as possible but i also heard a thicker head gasket will decress the compression a littlw bit, which would be good cuz i am turboing the motor?
