I just got running strong llc performance ones and they seemed very good. I talked to the company about how they were made, I made a thread on it here.
It was $140 for the set, they have some stock ones for $80 though.

I can't say anything about topline other than I've seen people say its cheap.

Only downside to Topline Valves is that they are a 2 piece valve as opposed to most other valves so they have a weak point where the 2 pieces of the valve are put together. I haven't heard of many horror stories with topline but when I heard that they were one of the only companies for dsm's who do a 2 piece valve I decided to go a different route and have mine removed. You should go check out engnbldr's valves on ebay, I believe he gets them from the same factory as Ferrea but its only like 120$ for a full set and their SS valves.

I cant' find the thread that explained how topline valves are a two piece but its somewhere on the forums.

Prety sure engnbldr is no longer doing valves. Read this very recently in another thread. really sucks cause i was plannin on using those 1mm oversize on my build.

His ebay listings have nothing for us dsmers now

hmm. I really don't know. My machinist said he's never had a problem with topline valves but i figured id ask on here since you guys know more about the dsms.

I put almost 2gs into my block. I dont want to risk it but im not looking to spend a fortune. Anyone else have any experience? Thank you to the people who put their 2c in

Topline is generally substandard parts and not very good. I do not know any horror stories on their valves. However I don't know anyone who has ran them. I would use the OEM ones and have them recut or lapped as needed.

Thanks

engnbldr I shearch this name since yesterday
I have read many threads about sheap valves but with good reviews from users here.
This is why i have bought this "brand" from the past , this vendor is perfect.
This is a link about standard size valves http://www.ebay.com/itm/EAGLE-TALON...7825197?pt=Race_Car_Parts&hash=item58b078bead

coltixim: You find any 1mm over from engnbldr? I searched everything he was selling on ebay and came up with NOTHING the other day. Cool you found it.

OP: Go to that link and buy those if you want stock diam valves. They have a solid rep and very affordable.

Guys... search my thread.

engnbldr is 70 years old and no longer stocking the valves. I was bought out by hours on the very last set ever to be made.
**Oh now I see your link, well those must be the very last ones he found laying around somwhere because he told me they had no more of any of the 4g63 valves...
But yes those are very good stock size valves.

I did extensive research on running strong llc and talked to the company. They seem very good.

thread for those that cant search.
