thanks joe and everybody else for the positive feedback, as for you henry your very much entitled to your 2 cents.
but what strikes me is that its much more gratifying for you to take the time in writing a extremely detailed paragraph with not one bit of useful nor positive information then to just help a fella out, its more satisfying for you to discourage somebody that has no clue on what he is doing but is taking the initiative in teaching himself something that most people in the culture have been doing for a very long time, i bet you have never been the type of guy to be casually strolling by a forum thread or a race track and had something insightful to say.
you rather be pointing out all the bad all negative rather then to lend a hand. but hey whattttever floats your boat.
for your information i have done research, hence the decision to go with a bigger engine then the stock 350 that it came with. have i read or bought books? how about 4. So please dont be so quick to judge somebody just because you might know a thing or about valves & cam's .
