valve springs....questions

[Old Guy with 87 GT]

jeff .....>update...i decided to go with a crane spring kit (44-308-1)
i did some shopping around and price comparison ,allthough the double springs you have are better and priced reasonably.......i called comp cams and priced everything i would need to run em .....i just don't really have the money .....the crane kit comes with everything i need and it's priced a little bit better in my range(poor "old guy" range).....the crane kit was recommended from a friend of mine and should be strong enough the run up to rev limit with 1.7s......hopfully i won't have a problem with them

jeff......i was however interested in that distibuter you have on your site......mine is a little old and warn (186,000 miles)......pm me on how much you want for it, if it's still available.......also how many miles are on it

i'm hopfully going to put the springs in this weekend .....i'm going to use air to do it with the heads on the car ......got any tips
