Re: First Flathead Build
Use a good penetrating oil and then give those stuck valves a tap with a wood block, or brass drift. Should free them up.

I've had more bad and expensive machine work done in the past than I care to admit. Please listen to others here, find another shop. If he doesn't think a torque plate is necessary, what other short cuts is he taking? |

Re: First Flathead Build
I'm no expert, and I'm sure having one honed with a toque plate gives piece of mind, but he simply doesn't have one. I trust him based on feedback from those that have used him in the past and I'm comfortable with any potential risk. I found this post here on HAMB, but I'm sure there are others that say the opposite.

I pulled a quote from the the thread you copied. I feel a flathead block falls into the same category as a Ford 302 block in terms of this. Think about it. There is a reason why Ford added 3 more studs to the block when it went to 239 c.i. A cast iron head clamping down on that deck with one big hole and many smaller holes on a thin casting is going to move. from what I have seen the lighter the block the more it needs a plate. A 302 ford will move enough to mesure but a big block 460 its hard to see. The ones I did we bored without the plate on a rotler bar then put the plate on the 302 pulls around the head bolts about .0015ish big blocks you could berly get .0002 |

Re: First Flathead Build
One of these pry bars will come in awful handy when pulling the horseshoe clips as well.
Once the clip is out you can sometimes pry up on valve from bottom, tap down and repeat, using lots of PB blaster. Or you can get the other tool here and make the job even easier. |

It may be stuck on from years of oil goop and muck. |

Re: First Flathead Build
"Sharp" - Just a question about an obscure item. Is the oil pump drive cover stamped steel or cast iron? Every Ford car 8BA I've seen had a stamped cover, while the Merc's (admittedly only two) had cast covers. Your's looks cast (maybe because it's a truck engine 8RT)?

Re: First Flathead Build
I remember making a 'slide hammer' out of a short piece of all thread (or a long bolt) and some nuts and washers. It just needed to be the same size thread as the idler gear center. It came out pretty easily once I got that rigged up.

Re: First Flathead Build
If you don’t want to damage the idler then get a puller. Screw bolt into threaded hole then pull slowly.
P.S. Tubman, I just looked at an 8 RT motor I have torn down, cover plate is stamped. Last edited by RalphM; 05-14-2019 at 11:28 AM. |

Re: First Flathead Build
Valves! No progress. Can’t get the horseshoe retainers off and can’t get anything going.
I won’t need to reuse any of these will I? Can I just cut the spring then cut the valve stem down low? Sent from my iPhone using Tapatalk |

Re: First Flathead Build
I just cut the valves to get them out.

Re: First Flathead Build
I had the same problems with my teardown. Ended up getting out the plasma torch to cut the springs & valve stems, then pulled the valves out from above (some with the help of a slide hammer) and drove the guides down into the valley. Only way to do it in some cases!

Re: First Flathead Build
This probably isn't the best way but it worked for me. Pry up the spring from the bottom and see if you can't get the 2 little keepers on the valve stem bottom off. If you can, then the valve should just pull out from the top. A little of the aforementioned acetone/trans fluid on the valve guides will help. I was then able to pop the springs out (wear eye protection). After that I tapped the valve guides down and out from the top using the right sized socket and extension.
