yes it should work but check to see how much clearance you have with those rockers and the valve cover. you may need to cut some baffles out of the stock valve covers if your using stock valve covers

with stock spring pressures, aluminum rockers will last for awhile if they are quality. I've heard they will fatigue under high spring stresses and lots of street driving. Aluminum is abit more fatigue prone than steel but alot of ppl are using aluminum rockers just fine. Some articles i've read say its just a myth that street driving hurts aluminum rockers. So i think you will be fine

you'll have to see about the leaning issue. mine i wasnt sure what happend. I was around 12.5 to 1 before the injector swap and 1.6 rockers. i think the injectors were not spraying right. Brought me up to 14.5 to 1 on the dyno. but that little extra lift may have got some more air in there, so it could have made it abit leaner. I thought the MAF would have compensated alittle for that so who knows

But i have had no problems other than that. I had comp mags, roller tipped
