[TR] TR6 Roller Rockers - any experience or advice?

[Brian Lanoway]

Ive been looking at a set of Harland Sharp roller rockers on eBay for my
TR6  with a 1 to 1.5 lift ratio that gives a fast road lift profile.
They apparently slide on with no modifications required.  Has anyone had any
experience with these?  Is installation really that simple?  Is there really
an appreciable gain in power while retaining a smooth idle?  If they are a
good deal, are there suppliers other than an eBay auction for these that you
would recommend?

Thanks so much in advance,
