We didn't order from a catalog or anything like that. I saved some money. Decided I wanted a new set of aluminum heads, intake, and carb. Pro Comp sold me a complete package for $1200. Shortly after I installed everything, the flat tappet cam went out. So, I then bought my Comp Cams solid roller cam and lifters set. The machine shop (buddy) called up Comp Cams and they sent us these springs. Obviously something is wrong due to the extreme bind in the coils on springs. I personally have never messed with valve train geometry before. This is all new to me. I never knew about coil bind and pushrod length. I am doing my best to learn here. Considering my poor math skills in school, I am amazed I even know what little I do. As for tools, you just stated buy some tools. Could you be more specific? About the only thing I can think of that I don't own is a valve spring compressor. I have a torque wrench, 60 gal Craftsman Compressor, all wrench sizes, all socket sizes, die grinders, bench grinder, mig welder, screwdrivers, hose cutter, feeler gauges, etc. Where I went wrong was trusting the wrong person at wrong machine shop. I will definitely be using a different one from now on.
