BTR Small Bore LS9 Head Gasket - 3.950" Bore - Sold In Pairs - BTR-058420-2. Sold as described below; installation labor and tuning are not included.
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.
