Re: New Snyders head
I ran two foundries for 30 years. The as-cast appearance in the combustion chambers is absolutely normal. I see no inclusions (sand, slag, etc.), no penetration/scabbing, no rat-tails, shrinkage, cold shuts, core shift, or visible porosity.
The head in the photo is absolutely normal. Should you wish a greater degree of finish within the combustion chambers take it to a shop experienced with polishing and CC'ing heads.
To sell a head with either hand finished chambers or fully CNC'd would add at least $100 to the end price.
Now, if you look at a collection of original Ford heads, bead blasted in the chambers to remove the carbon and reveal the original as-cast appearance, you WILL FIND a myriad of defects.
