This seems to be what most of the nmra factory stock guys are using for high RPM. I hate to even ask a price though.

While the jesels will never fall off due to their cup-design, they are substantially heavier than stock....unless you can find an older set that were 7000-series billet aluminum...and even then, stock followers have been taken over 9000 RPMs, if not more
GT supercar followers are around $400 a set, less if you can find a used set

GT followers are the best to get if you have the cash, they also raise the oil pressure in the heads as well since they bleed out 90% less. That is something the cam bores really like.

The GT (hydraulic lifters/lash adjusters) are smaller diameter, and are installed in a different head design! If your looking for the best high-rpm setup call John T. at Modular perf. he might not share his secrets but he could build up your heads for you
The intake are a smaller diameter and cannot be swapped to any other head, the exhaust rockers/followers are what we are talking about here. They can be swapped to any modular head, weight 5 grams less each, and increase the oil pressure at the head about 20%. The Exhaust lash adjuster from the GT is not needed we learned, the GT rocker works fine with the stock 2V lash adjuster cutting down the costs bigtime.

So 8 GT exhaust rockers per head, and it also slightly bumps the pressure to the cams. Cool to know.
A related question: How do you keep the 2V lash adjusters from collapsing at high RPMs? I'm thinking my issue was oil pressure, somehow...
Or was it my 233k mile adjusters?off topic: how do you guys feel about Cloyes timing chain adjusters/ tensioners? They seem to be the closest to stock I can find; oem is over double the cost. The plastic ones on my 03 engine really su*k.

since they're cast iron, I'm sure they'd be fine....how much are you finding the cloyes for?

Thx, GM! EDIT: missed your question: RockAuto looked like the lowest price.
The Cloyes friction parts look (96) stock, as do the adjusters. I can't put a front cover over the stock '03 ones; they're plastic and cheap looking, and newer cars chew them up and spit them out, from searching about it. And I found no complaints about the old ones, lol. Or the Cloyes.
Best Ford price (I found) for the tensioner alone was >$120. Each.
I need these, and the hold down for the "crack pipe" cooling mod, and I'm GTG with reassembly.

I sell the OEM Ford iron tensioners for $149 a PAIR brand new guys.
I had a couple people call biaching about the aftermarket iron ones having problems, especially whatever TFS is selling (don't know what Cloyes is using) The plastic ones are junk IMHO.
I know of a motor with 160lbs of spring seat pressure spinning to 9500RPM on the stock lash adjusters without problems so any problems you are seeing might be age/crud/etc.

sounds absurd, but then again, I don't even bother looking up MSRP when there are tons of online vendors offering stuff at cost + 10%
Tousley ford parts is one of my preferred vendors for Ford/OEM motorcraft stuff

I vote crud; I wasn't the original owner, and it had been Quaker stated at one time; there was a bunch of crud inside.
It still went 233k. If I hadn't done a pi intake mod and added a tune, it would have lasted much longer, lol. :facepalm:
I see some nice parts on your website; I'll be in touch!
