Agreed, but it depends on the mileage. I could never get my rollers (well, only one would fail, but that was enough) to last past 2,000 miles and that was setting them every 300 miles or so.

If you drive the car 500 miles a year, you are probably ok. Take out the lifters, rockers, etc. every two years and send in em for an inspection and rebuild.

I have a hydraulic setup now and it doesn't sound as mean. But it doesn't break all the time.

For a manifold, I use a Torker II, good for the street AND you can run a 14' air filter. I have a 1025 RaceDemon RS. Good carb, probably overkill. It has a lot of adjustments, and will pull clean from 1,200 rpms to redline in 4th gear, so its tractable for the street. Runs fine at 1/8 throttle. Idles rich though.
