Re: Flathead Lifter Adjusting - "On the Bench"

Hi Dale, yes, on the top, and once I spotted this and thought about it, even before I called Dave at "Topline", I knew it MUST have that crown in order to work the way it is designed now! There's a...

Re: Flathead Lifter Adjusting - "On the Bench"

The info I'm putting here today is more-or-less a "tip" about using the original Johnson tappets from Topline-Automotive, just got off the phone with Dave and learned something even I wasn't aware of...

Re: Flathead Lifter Adjusting - "On the Bench"

Hi Dale, with our head machine, working on one side of the block, we can machine AND install all 8 seats, have them all the same hgts (within a thou or two) by the design of the machine, then without...

Re: Reinstalling aluminum head questions

Make certain you use washers on the heads, whether you're using bolts or studs, we have "special" washers for this application!

(Add) We use Permatex #1 (hard-setting) on all our builds here,...

Flathead Lifter Adjusting - "On the Bench"

Well almost on the bench anyway? This is for NEW builds only. The method I'll place below here will allow the lifters to be adjusted while out of the unit! It's actually fairly simple and you MAY not...

Re: Spark Plug Protrusion into Head?

"Nailed" that one Jack, probably need a "hundred" or so! Don't have the time to figure the exact number out??

Thanks, Gary in N.Y.

Re: Spark Plug Protrusion into Head?

Anthony, if you can't or won't solve your plug issue with the washers then you'll need "spacers/bushings", these are machined as a 1-piece item. We've done this with a number of customers including a...

Re: Spark Plug Protrusion into Head?

OK, one more time, below here is a shot of heads I have here for another "pending" build, customer still up in the air!

These are a set of Offy "400's", still brand new, circa 1996/1997, these...

Re: flathead rebuild

Sorry guys, missed the end of this post??

We do the bronze-lined guides here, in house! You will never experience another "hung" valve where you install a set. Between the stainless valves we use...

Re: Spark Plug Protrusion into Head?

That plug is the number I used in my drag car (G.M. aluminum heads), it is a reasonably "cold" plug, worked well with the 13:1 C.R.

Here's a "cut & paste" from O'Reilly Auto parts:

Re: Spark Plug Protrusion into Head?

Just a heads-up, but to the best of my knowledge and as far back as I can recall all the "N" series Champions were 750" reach.

Believe I ran that series in my 13:1 468" years ago!

Thanks, Gary...

Re: 8BA Valve length

Hi "J", the lash caps are .080" thick, not sure this will help in Kev's predicament??

Kev, keep in mind you can also work with the valve locks to raise or lower the I.H.'s. Also, I would be...

Re: 8BA Valve length

Hi Kev, A few years back I fabricated some valve guides that are able to carry up to 5 .060" shims under the springs, the springs sit on "locators" and the shims "stack" between them and the guide,...

Re: Spark Plug Protrusion into Head?

While I agree about not spending a bunch of money on any heads to make things right you really need to keep things in perspective?

Just for arguments sake, if you were to spend as much as $400.00...

Re: Clutch chatter....

You really need a "dedicated" Flywheel grinder, this is the sole reason this machine exists, it puts the correct "scalloped" finish on every wheel and compensates for the "hot-spots".

Re: Spark Plug Protrusion into Head?

Hi Anthony, set them up now so you won't need any "special" plugs, it may all come back to bite you at a later time?

The most probable way we would end up "fixing" these Offy's we have here on...

Re: Spark Plug Protrusion into Head?

It comes down to the same reason that those "new" Navarro heads we checked out recently got "shot-down", by us anyway, some of the mfr's just don't care! It's sad but true.

With just about any of...

Hi Dennis, thought I was about to get proved "wrong" here, like I said, it's only really an issue with the Offy heads, believe me!

While we're doing the builds here, not that often with the...

Re: Spark Plug Protrusion into Head?

I can add this tonight, the total thickness of the threads on these particular Offy heads is .570", when you add the spark plug gasket thickness it's another .065", this gives you a grand total of...

Re: Spark Plug Protrusion into Head?

Just to keep the numbers straight here, we stock the 216 Autolite's, the thread length isn't .437", it actually measures .406" w/o the supplied washer and .343" with the washer in place! Obviously...

Re: Spark Plug Protrusion into Head?

The Edelbrock head in the...

Re: flathead rebuild

This "thinking" goes back to the old days where it really was a good idea to have the pistons on the bench right next to the boring bar/hone.

The times have really changed dramatically, we finish...

Re: Spark Plug Protrusion into Head?
