This head appears to be original and never used. The head is perfect with no cracks or repairs, P/N T2175. Run as is. $5,000.00
Oh my my.....how I wish.
Very cool set up. Tim
Looks like a good one and ready to go but not NOS. The top end is not Frontenac as they had a 2 piece shaft, no oil pressure in the middle and the rockers did not adjust, the push rods were adjustable. The stands are not Frontenac and the 2 nipples on the front left are not stock. The valves and seats have been changed and should be equal size. Looks like somebody put in smaller exhaust valves and seats.
These are not bad things and probably good upgrades but not a NOS Frontenac head. It looks like a good package ready to go but not a brand new Frontenac never installed. Somebody can make a nice speedster or racer with this package. Probably better than new and just a caution of how it is represented.
Thanks for the inputs. I am not a Frontenac expert, just lucky enough to find one. Or maybe it found me. But you won't find a better one. It looks perfect.
Does that head have one intake and three exhaust? Thanks, Bill
This Fronty head is a Model S, R or T and the model number should be stamped into the ridge for the rocker cover. These three heads were the same except for the compression ratio, and the Model R had stronger valves. This is when they were introduced and a lot has changed since then. Congrats as you came into a nice head. Bill
Glen states the part number in his original post "T2175". This head is the "T" model. One can clearly see that the valves have been replaced and exhaust hard seats installed. The "T" model head was the lower performance touring/commercial model. I know of several "T" model heads on the road and they all run strong and sweet. Very nice head in my book
Bill, Yes, one intake and 3 exhaust. It is a modelT.
I am not a speedster guy but would like to see the head in good hands and put to good use. I know it is expensive but you are getting a near perfect head.
Lots of interest but no money. Maybe it will go into my Model T museum.
Glen, Tell us about the 2 brass fittings toward the front? When you look in the water outlet are they connected inside the water passage with a short tube? Oil line to the rocker shaft I think.
Layden, There are two threaded holes. One on the side of the block and the other on the top. Both go into the water jacket. So you need to connect them with a copper tube to feed oil to the rocker arm assembly. That way you don't have to remove the cover to oil the rockers.
Layden, I was told by an expert that this was a bad idea because it would provide too much oil with no place to go. The holes can be easily plugged with brass fittings.
It's actually a good idea. You can use a hand pump to lubricate a little at a time without the need to remove the cover. Any excess oil will drain back to the crankcase through the pushrod guide holes then into the valve chamber. From the valve chamber then into the pan. Don't. know who the "expert" was that told you otherwise.
Mark, Your probably right, where there's a will there's a way. Hope your enjoying June Lake.
If you notice, there are small grooves/channels cut into the edge of each of the pushrods holes, allowing the extra oil to run back down into the engine.
It appears that the casting has already been notched from the low spots on the top of the head to the pushrod holes for oil return.
A restriction in the supply line would only need to allow a drip to the rocker system. As you say, just a slow flow would be enough, no need for pressure.
My original question was more about what fittings they used ( to connect the 2 we see) inside the water jacket where it is difficult to reach.
Layden, They are brass fittings.
Looks like they wouldn't have used any fittings inside the water jacket. They just had a curved bit of copper line that they pushed into one hole, then out the other. The two brass fittings just grabbed the copper line and kept water from leaking out.
Still looking for a serous good home.
