Erwin--
That engine is purty .... looks very nice

-- you did a heck of a job. In your initial post on this thread u indicated that you wanted exhaust heat, I think its a good idea. I would point out that Pat Smith who wrote the Multiple Rochesters article for inliners in their tech section claims to have had good results with exhaust heat, In that same article, Smith shows an exhaust plate he made using the intake gasket as a template. Whatever you decide---nice work pretty engine.
