We ran solid rollers in a 434 for 10 years and lifters were never an issue for us. We had around 5000 miles on one set. Valve springs had to be watched. We'd run about 2000 street miles or 1000 track miles on a set of Isky Tool Room springs. Cam was 264/272 @ .050, .660 lift, and 106 LS. We'd turn 7-7200 rpm on the track and short-shift @ 6500 on the street. It was perfectly happy putting around @ 2500-4500 as well.
