The car has 150K on it. The valve trane is all stock. I was planning on putting a low mileage short block in it, and having the heads gone thru at the machine shop. Then put in maybe an XP cam, and good springs. I will probably end up putting another 30k on the car before any of that happens though.

So is it worth messing with putting good springs on now? I dont have the heads off of the car. I will be putting the springs on with the heads on, and filling cylinder with air.

I do plan on backing down the shift point from 6k to about 5700 so as to hopefully help from breaking more springs.
