Thinking ahead when the time comes to replace the tappet rollers and mic the tappet block bores for clearance specs have any of you any experience with the fit and quality of the Drag, Dixie, or other Shovelhead/Panhead replacement tappet blocks either chrome or factory black. I know that I could have the oroginal blocks bored to size and purchase oversize tappets. Many ways to skin a cat as you all know.
No concerns at this time but the Cone Shovel is my baby and it is Christmas time after all. At this time running the oem HD hydraulic insers and the skinny Andrew's adjustables and all is good. :fish:
No experience with shovel blocks from Drag and never heard of Dixie but I do have some experience with honing (not boring) the oem blocks for oversize lifters. IME, honing is the way to go as long as it is done by a knowledgable machinist. Not saying the blocks from Drag are not sized correctly, but there is no way they can be as precise as having a machinist mic each lifter and hone each hole for a precise fit. Plus I think the iron used in the oem blocks is superior to anything coming out of Drag today.
Thanks Turboprop,
Sounds like keeping my oem blocks and going up one size on the tappet bodies will be one good option. No need to tear it down at this time. Afaik the tappet bodies are from the factory, rollers checked good when last in cam chest.
Carefully mic'ing them of course is the starting place, but frankly, I'd be surprised if they need honed. Unlike EVO and later blocks, them's cast iron. As in, "wears like iron". Unless the bike was poorly maintained and ran for long periods with dirty oil, the tappet blocks are probably fine.

Daytona Japan makes good lifter blocks
Thanks JW and JSD. I know there are some very knowledgeable shovel wrenches lurking here and help was on the way.
For now the FLH motor is good to go; :chop: :chop: just looking down the road as it is a hoot and a holler to ride and enjoy.
I have a set of Dixie ones here, made in Japan. Chrome is nice and the lifter fit is good.
Stock cam I assume
Sifton Cobra 112, mild .440 lift, works with solids or hydraulics.
Personally I'd upgrade away from stock shovel type hydraulic lifter design and go with something like S&S or Velva Touch, have them fitted to your OEM blocks if they are compatible.
Or buy a complete set from Velva Touch, new lifters fitted to his new blocks by him.

Thanks Velva Touch and S and S top shelf parts. Appreciate everyone's input, at this time Murphy's if it ain't broke don't fix it comes to mind. I do have a Shovel fund started.
I'm thinkin that jar should at least be a jug. (or like my extra large coffee can) :teeth:
