They can rust in quite solid, penetrant, heat and more penetrant.
Its off, crankcase split, piston out (3 piece oil ring type) crank out.

Do I change the lower main bearing?

where do I buy gasket kit, rings & seals?

I was bored so I decided to give the head a porting job.
before I started you could not see into the ports from the combustion chamber. I wish I took a before photo, Its a huge difference, maybe some one has an original head laying about?

this is my 1st go at the inlet port to take the sharp corner out.

Exhaust 1st cut to take the corner out.

Don't know if this will make a noticeable difference but Ive got the tools so no harm in having a go.

Except for Bert, I feel like I'm talkin to myself in this thread but whatever I'm having fun.

Your views are high so people are reading. I personally try not to cause confusion by piping in when someone is already taking care of it.
