Opinions......Ported Heads w/ Stock Cam??? What gains could I see from getting my stock 241 heads fully CNC'ed and hand finished while keeping my stock cam? Reason being, I want to avoid the lope and keep certain others thinking I have only a bolt-on car. I'm also considering spraying the car, would the heads help the nitrous gains in any significant way? Thanks!

You would gain between 20-40 RWHP with decent ported heads. I know AFR heads on a stock cam 2003 C5 picked up in this range. Do a search, Vinci performance did the work.

Untouched LS6 heads have shown 10-15 rwhp gain on stock LS1 cams. So after thinking this through, 30 probably wouldnt be out of the question. With all the bolt ons, and the rocker arms, you could see very healthy gains! Id figure another 10 out of the 1.8 rockers and you could run 918 springs for a light valvetrain.
Im contemplating the same notion as my current situation is not a drag race friendly one and i drive the car every day. id like a set of ported heads with all the bolt ons. Wonder if 400 rwhp is attainable.

Add ported stock heads: 20-25 rwhp. Add AFR 205s: 35-40 rwhp. If you want to look and sounds stock, but make more power, check out this thread: https://ls1tech.com/forums/generation-iii-internal-engine/311937-395-rwhp-na-factory-manifolds-cats-catback.html
