SE 110 heads
Hey , are the SE 110 cylinder heads a good choice for a hot rod build ? I've been seeing a whole passel of em on the market lately . Any pros and cons of using them over a set of factory 96" heads on a mild 103 build up ?

To be honest if you have a good machinist save the money on the heads and use the 96" set. the 103 and the 110 are the same heads I believe ( Don't quote me on that). My 106" has a set of heads from the stock 96" and they were able to machine out space for a larger set of Int and exh valves. Also for a hotrod I wouldn't use the compression releases and try a set of S&S easy Start cams with the compression releases built in. If you do the head work from a 96 you wont want to weaken them by placing the compression releases in there.

Those heads are better suited to big inch motors. HD had a recall on some of them & didn't ask for the cores to be returned. Probably why you're seeing a lot of them out there.

The guides weren't installed with enough press-fit.
But once that is addressed, and perhaps manual releases installed, they seem to work very well in larger engine applications.

Makes perfect sense to me.

So , after the new guides are installed you have a good set of heads to work with. Are the specs on the 110 heads the same as the 103 heads? Valve size, chamber ccs, port volumes? Would these work on a pumped up 103? Thanks
Anyone know where I can get the specs on the SE 103 heads to compare them to these 110s?

The 110" heads have a Ferrea, nail-head design, 2.080" intake.

I saw a storage semi trailer at a pretty good size dealership with boxes and boxes of them that were recall cores.

What Scott is trying to say is "in the right hands and on the right size engine, they perform great!" Right Scott?

Rob,
Yes, that is correct.
That "T" shaped head design, or also refered to as a "nail-head", acts like opening a door, when coming off the seat. GULP!!! Only way I know how to describe it.
Better stock up on tires!!!

Okee dokee Nail head, I get it (sorta..close enuff)
so what size build would you say was minimum to make good use of these heads? understanding that H-Ds will swallow just as much money as you throw at em, would these heads be worth working over comparable to "custom" heads?

make good use of these heads
117"+, or very hot higher rpm 110"
The only way to pump the torque up with these heads is to use a short cam and they die early such as the SE255. Use a Woods 7 or TW400 for a compromise and if you let them go with a 250°+ cam the torque and hp numbers swap, HP exceeds peak torque.
