It's not a rough idle, not like a 292 atleast, it's a nice slightly lumpy idle. I don't run it in any automatic vehicles, so i can't tell you, but it shouldn't have any problems off idle. Well, what does your's idle at? What are the front/rear gear ratios? If you're worried about the chip, get one burned, if you're worried about the heads, trim the upper valve seal. Trimming the valve seals is very easy, but you'll need a valve spring compressor. I've never placed a cam into an engine with as low miles as your's alone....I've always replaced cam and lifters together, except with roller blocks.
