It's costing me parts, I work at a race engine shop, part time. Free use of the equipment is part of the deal; obviously, paying customers have priority. I'll let you know what normal cost would be tomorrow.
In this case, caps are 440 source aluminum, bought off C/L from some one who was going another direction with their build.
New caps will almost certainly require align boring, which is kinda PITA; align honing is just good practice on any build. S/F.....Ken M
