I found a deal on a set of new Screamin' Eagle Performance Heads that I just couldn't pass up. I plan on putting them on an '05 fuel injected 88ci Road King. It is currently stock except for the Stage 1 flash and SE exhaust. According to the SE Catalog, the heads should raise my compression to 9.5:1. Which Andrews gear drive would be best with this setup, the 26G or 37G?

use a .030 head gasket and use the 37's...
you might as well do the 95" while you have the heads off, not much more money or time and totally worth it IMHO...

Another option is the woods TW-5G cam that was designed for those heads.

I would call Andrews and they will recommend what cam is best suited for your build and type of riding you do.
According to there website they know longer take those types of calls. They do have a chart though.

Or you can email their tech line from their web site. This I know is still functional since last month I used it to get a recommended cam for my father in laws build.

FWIW...he has the SE heads, 95" flat top pistons in bored jugs, SE ignition and coil, Dakota Kid 42mm carb and V&H ProPipe...and they recommended the Andrews TW-31G or the TW-55G. He went with the 55 and seems to be very happy with it so far....I know I like the 55G in mine.

Where you from in MN, Harleyhinzy? I'm in Mankato.

I'm running the SE Perf Heads with cast flat top 95" and a TW 31G , with the Cometic 0.30 it's a good setup . The 26 and 37 won't do well at the compression this has (10.2) this is a nice torquey set up , same lift as the 37G, S&S 510 or Woods TW6 .. IF you want to go with roller rockers the Woods TW5G is a great choice.

Seahag,

When you installed your 55G's, did you have to remove any material from the bearing boss like the instruction sheet states may have to be done? Just curious.

ceannas,

FWIW, I have installed the 55G cam in an 04 and 05 night train and did not have to remove any material....both had ample clearance. You will need adjustable pushrods though.

No...plenty of room with a .550" lift cam. Wasn't even close really. I did have to do some grinding of the cam cover to clearance the primary gear drive though. Gave me a good excuse to buy a dremel tool set.:brows:

Nidan is correct, but the TW5g will work. With the short duration the added lift after port stall will allow more cylinder fill.
