Stripping the Lotus Twin Cam head down is a fairly straight forward process. With Miles Wilkins book in hand, and some tips from the community, it takes about 4 hours. It's now ready to go back to the machine shop.
The camshafts and the exhaust valves all look good. I was concerned that cylinder 3 exhaust valve was sticking, allowing oil to leak into the cylinder, but the port looks clean. I imagine oil was leaking onto the hot exhaust and hopping up onto the block.
I have ordered new gaskets from Burton Power in the UK. The new head gasket, made by Cometic, is composed of stainless steel and has bonded membranes so that adhesives are not required.
