My home inspection of Speedmaster heads

A couple pics of the things I've noticed, nothing show stopping at all. I'll post back with valve guide clearances when I get them apart.

The shavings in the exhaust bolt holes and a bit of flaking around the guide support bosses. Intake ports are matched to the gasket, I don't have an exhaust gasket on hand.IMG_20191211_173136.jpg IMG_20191211_173030.jpg IMG_20191211_173503.jpg IMG_20191211_173409.jpg IMG_20191211_173701.jpg
