Do they contribute to excessive valve, valve seat, or valve train wear? If you have them or have used them, I'd be really interested to hear your experiences. I have had a set of 1.25 ratio rocker arms on my Camper for three years along with S&S headers, Dynomax muffer, K&N air filter and synthetic oil. I haven't done any quantitive testing, but am happy with the way the van performs. Fuel mileage was not effected significantly, it still gets between 19-20 mpg consistently. Oil consumption did increase to a quart every 1500-2000 miles after I installed the rocker arms, before the installation the motor used no oil. I would recommend installing them only on new or rebuilt heads, not on ones that have any significant mileage on them. Good luck,
