Since I am getting a new head, with out cracks etc.. I was wondering about ceramic coating. If a head gasket was overlaid on the face of the head, and the prechamber was covered, could you coat the exposed portion of the head? The valves would need to be pulled and the seats touched up for sealing. Don't care about coating the inside of the intake, but will be doing the exhaust valves and ports.
Can it be done? If the top (head) and bottom(pistons) are done, do you think it will offer much of an improvment in burn efficiency / spool time? I wonder if it would stop the cracks from forming?
How much heat do these coating block???
Thanks,
Having used the search function prior to posting my question, and having been familier with that thread, I did not see my specific question addressed. That thread covered mostly the prechamber and the inserts, color of coatings, and theory. I do not intend to coat the prechamber or the iconel inserts, nor the intake tract. Exhaust valve and exhaust tract, yes. Perhaps also the face of the intake valve, but that is minor. I understand the heat benefit of uncoated prechamber inserts.
My question was about the value of coatings on the faces of the cyl. head that are exposed to the combustion chamber. Dave had mentioned he coated the entire head deck. Specificly, I am wondering if the heat blocking properties would improve the combustion / burn by keeping more heat in the cyl, and out of the head. By doing this, would this also help prevent the cracks from forming between the valves? If the coating did help keep heat out of the head and allowed more heat to be applied to "work" would this create a effiency that would translate in to the possibility of quicker boost?
Thoughts?
If the moderator wants to move this and join it to the previous discusion on ceramic coatings I am fine with that.
