DIY... Harland Sharp Roller Rockers
roller rockers offer less drag on the engine. you can also get a higher valve lift for a slight increase in performance. win win on all levels so long as you don't get valve kiss on the piston. I want to put them on my 350 v8 boat motor this winter. Turning 3500rpms all the time will benifit from the lower friction of roller rockers.

I am about to do a list of repairs under the hood- Radiator, Plenum, thermostat, water pump, fan clutch, and Cat gut. Do you have a part number or link to these rockers. I was also wondering what the other fella asked, could this cause any premature damage to the valve train by running the stock springs? I was always told to have the heads rebuilt when doing something like this. I could see caming it out would certainly call for new springs.
UPDATE- Nevermind. I don't have 350 bucks to spare.

Nice write up, they sure do look perty! Have you noticed any difference with them? I would assume they would be a bit more quiet too? I'm about to do a crate motor swap and will slip those on before it goes into the truck, just curious if it's worth it.
I think they are worth it. I notice more lope at idle. The sweet spot for my truck is about 3500-4000 rpm. can't really tell if it's quieter or not due to my loud muffler.
I noticed the same lope as well I really like it, they say they are worth 3/10ths on the quarter mile and was also told same as adding I I noticed the same thing and love it just makes it sound differnt they say it will drop your quarter mile by 3/10ths
Also was told it is like adding a cam with 0.060 lift. About $300 for the set worth it to me for sure.
just noticed the date of the first post someone went digging
