Hello Goodwrench, welcome to the forum! I was in Morgantown several times back in my college days when a buddy went to school there while I was living in the DC area. My buddy and his roommates lived in Pierpont House, and they and their friends were known as
The 5 O'Clock Club. That was quite an experience. I even rode my H2 there a couple times.
- You should do a leakdown test of the crank seals before you get very far along. They may be OK, but at almost 50 years old, they may not be.
- The old Denco porting specs you posted will reduce the bottom end torque significantly, and make it peakier with a bit more HP, assuming you also have 34mm carburetors.
- The compression will give you problems. You should get that down to the 155 level or below before you bother trying to ride it.
- The L55G plugs are for drag racing. I ran them for a while because the Denco specs for that porting recommended them. They're extremely cold and will give you lots of fouling problems. Stock plugs, NGK B9HS work very well for street use.
Running the bike as-is might not cause problems, or it might melt a piston from the high compression.
