looking for some roller followers, besides Jesel and trickflow whats out there?
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
So 8 GT exhaust rockers per head, and it also slightly bumps the pressure to the cams. Cool to know.the GT rocker works fine with the stock 2V lash adjuster cutting down the costs bigtime.
since they're cast iron, I'm sure they'd be fine....how much are you finding the cloyes for?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.
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%Best Ford price (I found) for the tensioner alone was >$120. Each.
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.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.
