Default Re: Rebuilt Flathead Problems.

Bored&Stroked here is what I have. My valves are 4.890" to about 4.905". Not sure if they were ground on the end or not as some of what the builder did I cannot be sure of. These are 2 groove valves with the groove closest to the end of the valve supposedly for the lock and the other for the seal. The above not withstanding I again measured my installed height, and thank you by the way as your question made me recheck all my measurements. Earlier I had confused myself by adding a ford valve installed height (2.125") into what I was doing and that just made things worse as my thinking then became I had to somehow match that measurement using the chevy valve and springs. So this morning I installed a chevy valve with a normal retainer (not rotator) and lock in the second groove of the chevy valve with the horseshoe clip. I got an installed height of 1.950". So with that as my working height I measured a spring at that height and got about 50 lbs. I added a .060" lower spring retainer (Gary's machined ones) to the spring and checked it again and got 58 lbs. So I have assembled my valves using that info and process. I know there are folks who come out on either side of using the second groove and not using it but to be honest the lock seems to fit better in that groove than the other one. Plus some of the folks who say it is ok are guys that have done a serious amount of flatheads. So good enough for them is good enough for me.

I still have 2 issues. First is I still need 1 more normal type retainer if anybody has 1? Happy to pay for it plus shipping. Second is I need to install the seals on the intake guides. Does anybody have any tips on making this easier?

Gordon, do you need the round piece that goes above the two keepers and supports the bottom of the spring? I think they are different for rotating and non-rotating valves. I am almost positive I have some of both kinds. I didn't get to my shop today, but I will tomorrow. I'll lete you know tomorrow afternoon.

OK. I'll send a couple. I had to ask because there are so many valve types that have been mentioned that my head is swimming.

Tubman I hear that. I have had 3 sets of springs, now 4. Multiple sets of valves, chevy and Ford. Two types of retainers/keepers. Multiple sets of guides, one set completely machined. Three different install heights! Man my head is spinning too!

Guys I have finally started installing the valves now that I have gotten all the parts needed. Got through most of them pretty well but did damage 2 of the guides and need replacements. Thanks Gary! That was probably more due to my inexperience with the pickle fork than anything else. Had a real difficult time of it until I ground the leading edge of the fork fingers down a bit. Once I did that I could get the fingers through the progressive wound spring and onto the guide for a decent register and that allowed me to pull em down and install the clips. For those that are still tuned in I used chevy 1.5" valves. I used the top regular lock groove on the valve. Normal retainers, not the rotators. I used a 2.480" spring. I had to use 5 .060" shims plus Gary's retainer which is also .060". This gave me the 67 lbs pressure I wanted. I set the lash at .010"/.012" for the intakes and .014"/.016" for the exhaust.

This thread has gotten way longer than I had ever dreamed but was a good exchange. Going forward with the rest of the reassembly, install, and attempted fire up of the motor, I am going to do a separate post for that as it should be pretty straight forward. (Kiss of death right there!) Anyway here are a couple of pics.

Gordon,

Keep at it! I'm sure the results will be worth it! If nothing else, it will help a lot of other folks here facing the same problems.

Glad you are making real progress. I have one of those long bar forks and a much older one from back in the day. The end of the older one has quite a lot of subtle details in the shape of the fork.

Keep up the good work.

Mart.
