you can only ask yourself these questions. i say if you have the secret cams throw them in, why not? and the ho mani, thats on you.

on a stock car with just the mani yes, but with cams/ported head and a full exhaust i could see there actually being a gain

So long as you have a proper phenolic adaptor flange, or an LD9 aluminum flange welded onto the H.O manifold, you're wasting your time with it.

Cams are a yes.

Be prepared to re-tune the car.

I would dare to say it will only bring it back to about where it was (not knowing the full gains from the head and cams, but assuming it won't be more than 10 hp without a tune). In the thread that was posted, IIRC Mastin was running ho cams, and still posted a 7 hp drop. Now, I can understand a gain on a good n/a build (But you know most people who will consider buying this probably aren't going to build or even tune).

IMO, I wouldn't even bother with it unless you are boosted, built for n/a, or just going for show.

It is a good looking piece. But to me that is all it is.
