[QUOTE="Faded, post: 665076, member: 38322"] You can kill two birds with one stone and run a thinner base gasket (Cometic makes one). This will lower port height and increase compression. If it doesn't work out you can always reverse the change. Also you can add a couple of exhaust manifold gaskets to change the tuning length of the pipe to gain some bottom end. Something to think about... :think: [/QUOTE]
