I believe the consensus was that Integral cams were very good, but the company is now defunct. They were cheaper than anyone else's cams and went out of business quite some time ago. Ideola found someone who was doing regrinds of their profiles, though for quite a price.

Yes, we can still get Integral profiles done as a hard-faced cam. Last few I did were in the $650 range, so not cheap. I have two of my own that I'm planning to have reground, so I'll be checking current pricing from the supplier shortly.

As for using a Turbo profile on an NA build, I don't think it would be awful, but I would strongly recommend sticking with a Stage 1 for any car that will spend any amount of time on the street. If you plan to supercharge, I think either NA or Turbo profile will be adequate, but I would lean toward the Turbo profile if it were my project.

Not dishing Integral cams in anyway, I have never used one. I went down the path of having a cam reground and used spacers on the tips of the valves - saved a LOT of money. I used Paeco, great people, very friendly and easy to deal with.
I used there POR-7200 cam with an 11:1 motor in my race car, stock internals aside from forged custom pistons to give the compression and still using CIS. Although this motor is in a race car it would be fine in a road car.

I got the valve spacers from these guys: http://www.precisionshims.com.au/

I remember paying something like $30-$40 for everything I needed plus a few extras including shipping. They are very good quality and very reasonably priced.

So you're saying instead of a bigger cam you used spacers? And it works the same?

Why has this not caught on and replaced bigger cams in general?

For valve lash, spec tolerance gap between the cam with the valve closed/lobe up and lifter.

It has an effect on valve lift if it's out of spec but this is not a way to increase lift, it's to get the tolerances correct..

Shims are used in two scenarios:
1. Stock cam that is ground down to a different profile which requires a shim to maintain proper valve clearance.
2. Any cam that uses a solid lifter such as the Sten Parner units we had commissioned a few years back.

The Integral profiles we are currently producing are a "hard-faced cam", which is a weld-and-regrind approach, which maintains proper cam circle and eliminates the need to use shims, unless you're combining it with solid lifters.

The Paeco and WebCam options are simple regrinds on existing stock profiles. Some have postulated that this approach will accelerate lobe and lifter where because the lobes necessarily become more pointed.
