GT-40 upper and lower intake/ replaced head gaskets and port matched the heads sorry no pics of heads, Just thought i would share some pics of my grief the last week roughly 20 hours on the heads, those exhaust ports are tiny with huge themactor "spelling" bumps. Again sorry no pics of the details I wish i took more pics.

I noticed A good difference in power, sound and throttle response, but I also ported out the intake and exhaust ports on the cylinder heads.
