Yes it does. It is a very good guide to how your engine will turn out. Of course the better the information you input the more realistic the result.
I've read through the Hughes website, and yes, they explain why their cams are better. The Crane website lists why theirs are better, the MP website lists why theirs are better. I was trying to get the opinion of people who have had more experience with the different grinds/manufacturers. I'm aware of Hughes and their reputation.
No,no,no. You are reading the SALES pitch.
You need to understand how a cam works, what cams do to make power, what parameters to look for. Then make an informed choice based on sound physics and theory. NOT hearsay or sales pitch. I always point people to the Hughes site whether they want a Hughes cam or not because it explains cam theory better than any I know. Too many people just do what other people do. Don't fall into that trap.
Do you really feel that my 452's flow better than 906's. I have a set of each to choose from.
As stock they flow about the same. If you have both put them side by side and compare. You will see they look the same. Up to a point they can be ported the same. However the 452s can be ported out easier when it comes to a really big port job. The 906s need a little welding. Plus as you say the 452s have the hardened seats already. So they are perfect for the home port job you are thinking of.
The templates are fine for a mild street/strip engine. Use them to define the size and shape of the ports. Then blend it all together so there are no 'steps'. Shape the valve guide into a teardrop shape and smooth the edges on that too. Get a three angle valve job as well. There are also valves on the market that flow better than stock.
