lane_change

Yea. I opted for the Titanium intake and Inconel exhaust valves. Got the tracking number today. Should have them here shortly. Now I need to order some new head gaskets. The gaskets on the car when I pulled these heads were for an LSX 4.200 bore but I'm debating going with RHS 4.165 bore .036 head gaskets but that would put me just north of 12:1 compression which is getting up there for 93 octane.

If your bore is 4.165 you would need something around 4.200

You don't ussually run the same size gasket as bore.

I think we used the 4.165 on my 4.130 bore motors
