BTR SMALL BORE LS9 HEAD GASKET - 3.950" BORE - SOLD IN PAIRS - BTR-058420-2
The BTR LS9 head gasket can't be beat for performance and value, but traditionally, the smaller bore engines have had to make do with a head gasket bore 0.15" bigger than needed. By re-designing a smaller bore gasket, we increased the amount of gasket material between the bores another 0.15" for better durability . This is advantageous on small bore LS engines with higher cylinder pressures such as those found in power adder applications. These feature .055" thickness spread across 7 layers of steel.
Install tab towards front & added coolant passages to the rear
DESIGNED TO WORK WITH A TRICK FLOW FAST AS CAST LS1 HEAD. May also work with other aftermarket cylinder heads.
