Ok I have a question about lash adjusters, I'm getting a set of heads P&P and I want to know if I should get brand new lash adjusters or just reuse the ones off my heads which have almost 60k on them? Also what are RFF's? I did a search for this but counldn't find anything on them. Just to give you some info. they are NPI heads with PI cams going on them.

I reused the ones out of my heads when they were PnP'd. I think mine had about 60K on them IIRC, although it could have been more. I've put about 5K on the heads so far, and have not seen/heard anything that would make me suspicious about them having troubles.

If you got or are going to get the heads P&Ped, why wouldn't you go with FoxLake's Solid Lash adjusters?

Because you'd have to take off the valve covers and adjust the lash every so often, and the power increase is negligible at lower rpm ranges anyways. You won't be turning the stock motors more than 6000, so you won't see much benefit to them. Plus, many people just don't like all the maintenance. The stock pieces are great from the factory. I'd go with them.

EDIT: Damn, beat to the punch!

FYI, The fastest N/A Tbirds are running them. I know you have to adjust them but...

Oh well just a suggestion.

Unless you plan on running above 6000 rpms regularly, it's really not all that worth it. Having to manually adjust them is an annoyance, and I'm also told they're loud as ****...

Not only must you adjust them, but if you don't you'll get decreased performance of even motor damage, AND they cost $400 ($800 for 4V).

Ok Jim saw my question and answered it about what was a RFF’s. For anybody doing a search in the future it stands for “Roller Finger Follower” I went and got a picture of it that I will link for people to see.

RFF's

The RFF is the green rockers

I'm not using the solids,and KD saw absolutely no gains by switching to them.

I'm not gonna say that..KD and I are both running lower lift cams than most of the guys(less than .500"),and at higher rpms with the higher lift cams-they might help prevent some bleed down from the increased load,but I'm not 100% convinced that they work well enough to justify the admission price.

Point is, unless your a full out drag racer running 10K RPM and Crower cams with .612" lift @ 1.8:1, the solids are a little pricey and not much bang for the buck. Thats about all I can gather out of this thread in regards to if solids are worth it or not. Tell me I'm wrong and correct me please.
