A bit of advice. Years ago I had a builder with a good reputation build my old 406. It was over 10 months from the time I dropped off the short block until I picked it up ready to run on the dyno. I realized costs would be high but I felt I was prepared for a little over budget. In the end the cost was waaaay over budget. I had a heck of a strong engine after it was done but way over my estimated costs. MAKE YOURSELF A BUDGET AND STICK TO IT. I listened to and trusted him a little too much and his cost was actually not cheaper than the catalogs. Keep in mind builders and machinists have to make a living to, you just need to decide how much of it will be at your own expense.
Unless you are going racing do you really need the most expensive set of heads or the most expensive cam? Just food for thought from someone who has been down this road once.
Use your own head and invest your time to research what you need, and shop for your best prices.
This kit looks pretty good price wise and I've heard the quality is good to!
