Manley Custom Valves

Manley has had the U20 valves for sometime now. They're the best and a bit less expensive.

I did not know they had "on the shelf" parts.

There many makes of valves better than Manley, but it is still good to have the source if so.

Intake and exhaust? Part numbers please?

25 ea.for custom SS w/hard tips is pretty reasonable, but if you would rather buy Manley that's cool too! Cheers j

Just got up here. I can't find the receipt in the list of rebuild parts for the head but i'll pull out the ol roadster expense file the wifey has and let you know.

Doug

I'll call Manley this week just to check 2017 prices. Highly doubt they have an off the shelf part, but its possible//thx jt

So if Manley valves are not the best what specialty valve manufacturer made yours or which manufacturer would you recommend above all others for quality?

Doug

There are several other specialty manufacturers that are excellent. Ferrea and Del West are outstanding.

The group I use for valve manufacture does mostly turbo Porsche & M-series BMW components. When the engines start at 25k, you don't really play around.

Since stock valves at over 30-40$ each, these are a nice option and are very high quality.

As with everything, you are free to buy your items from anyone. If you have a favorite vendor, I always encourage that!

No Manley off-the-shelf production valve for U20 or R16.

Manley is $30 each for custom SS w/basic features, nothing elaborate. 30 does not include hardened tips, that and other special ops (swirl, undercut etc) at additional cost. FYI

Its been 2 years. Stupid me. I was looking for a Manley invoice forgetting that it was a Manley part sold by Datsunparts. I found a sales receipt from them www.datsunparts.com/2510


Doug

Doug, no Dean, no Doug, wow I'm so confused!!!!

Unless your best girl wants me to post links directly to my parts in his threads (or have MY best girlfriend do it), perhaps you can limit your replies to the threads he creates?

Anyone who knows my products knows the quality speaks for itself. That's why folks can buy many of my products from:

Ross Mullen
Mike Young
Don Morrell
Stan Chernoff
Dave Premo
Paul Wells
Lou Mondello

I never questioned the quality of your product at all. However you remarked about there being better valves than Manley. You did that. I don't know those other fellas. You were also the one that raised the question about Manley valves being available or not available I just answered. Jeez, don't ask and I won't answer. Nuff said.

Come on man, we aren't stupid......these are the statements you made on a thread specifically announcing a new reproduction part:

Manley has had the U20 valves for sometime now. -no, custom order.
They're the best. - nope
And a bit less expensive. More than my posted price

Every statement was incorrect, And then you post a link directly to d-parts.com-
This is all an innocent coincidence?

My sincere apologies if I was mistaken, but I don't think so.

Gentlemen

Let's bring this discussion back on topic. Posts of technical and commercial nature related to "Stainless U20 Valves, springs, guides" as offered for sale by JT68 are welcome.

Further posts about other valve suppliers and performance, third party interests or speculation of third party interests won't be tolerated. I've not deleted any posts as censure is not popular or effective solution but the offensive threshold is in sight.
