See...Progress without money ...yet. YOu can alway scuff the bores (ball hone) to break the glaze, then toss the thing back together with fixed heads..That step on the port roof hurts a bit...And the seats were never cut for the larger valves?
I'll know more about the heads when I pull the valves out. The seats look like they were cut for the valves.
I'll have to look closely at the rings and also check the end gaps to see if they will work.
I have to do a bit of searching and find out what pistons these are.
The number stamped on the top is 3690825 but I don't know what make.
They also have 340 and .030 stamped in the top. The good thing is whoever put it together stamped the cylinder number on the top of the piston, so I won't get them crossed up.
The heads # is
