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.

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.

Okay, so this spring the bird's getting a built 2004 trans and 3,500 stall 10" TC from Alan, with the expectation that next winter will bring ported heads and cams. I've done some looking around and I'm thinking about going with Nick's stage 2 PI head and stage 2P cams combo, with the modified...
I'm trying to drain the coolant to change temperature sensor, sender and thermostat. I have unscrewed the petcock almost an inch and only getting drops of coolant. It won't unscrew anymore. Any suggestions?
Okay, so two years ago I got the P1443 and replaced all the evap hoses with fuel line and both electrical parts. I should say, all but one hose, the one closest to the fuel tank. I was pretty sure I could get that one off, but not sure at all I could get a new hose on there because it looked...
Hey guys, it has been quite a while but it's good to be back!
I am in need of some guidance regarding a recent engine swap in my 97 bird.
The back story:
It has been quite a while since I have posted, mostly due to the fact that my motor exploded roughly 6 years ago. Since then the car has...
I've got an issue I've been working on on the Tbird for the entire time I've had the car; and I know it's a wiring issue somewhere.
I've swapped a bunch of stuff, but can't find it.
I have all the drawings, datalogging, electronic skills, everything I should need.
The problem is it runs rough...
