Crossover Tube and Valve Spring Pressure Questions

Here's the thing. There's ALWAYS better cam choices. Know what I mean? Somebody somewhere will always say that and to some extent, it's true, I guess. But here's my argument on that. If you already HAVE one or have one ordered, there is no better cam choice. Unless it's so badly mismatched that it will be a dead dog no matter what you do and yours isn't. If you install it more advanced, run a good loose ignition curve, you can tune it to run well. Isky grinds some fine cams. They have a LOT of "area under the curve" as they say. Plus, that grind is a good, old school grind with lazy and slow ramps that will actually be GOOD on the street and be easy on the valve train without smacking the valves open and then slamming them shut. There's a lot of good about that. What did we have before the latest and greatest fastest rate of lift cams? Cams just like that Isky and they set lots of records on the strip and won lots of street races DECADES before anyone knew what a fast rate of lift cam was. So don't sweat it. Run it.
