Stock cams are the way to go in my opinion. The little extra hp is not worth the headaches that comes from the ecu(obd1). I think the obd2 is a little smarter and can correct everything that the cams cause. I am running stock cams and the motor runs out great. Never a crazy idle or anything weird.

When my timing jumped (about 11-13 teeth) it ended up being valve to valve damage.. however at least two intake valves I think it was is maybe about 1 mm bent

25D heads the valves are closer to the piston tops, and at a steeper angle. That's why they hit pistons. Additionally, they can be valve to valve interference too, if the IN. and EX. Cams get out of time.
