The right tools make all the difference. The Crane valve spring tool is perfect for this job. Don't use one like below. Also, if you make a wrench you can use the TDC method and won't need an air hookup.

the rope takes up room in the chamber and is a soft cushion for the valves to hit on.....a lot of swaps don't need this but like on my big block, it holds the valves up higher and makes things a lot easier to do and it sure beats an air fitting.........every day is a school day!....good luck.....

I have done the rope method as well, it also helps if when compressing the springs the keepers are stuck. Just make sure a rag is in all drain back holes and over the valves when you compress them.

My TFS heads are only about 9months old. Should they need new valve stems? Im only upgrading from Patriot Gold Springs to the Patriot Extremes. Trying to prevent valve float, presnt or future.

Thnx for the advice guys. So let me get this straight, 1) hookup air comp to spark plug threads to keep valves up, 2) use spring remover by following the instructions, 3) replace valve stem seals by pressing them on and replace springs.... repeat 8 times. Sound right? Do the stem seals come off easy?

The rope stuffed in the cylinder at TDC sounds like a neat trick instead of using the air pressure tool in the spark plug hole.

From someone who had a compressor issue and saw the valve drop into the cylinder, the rope or TDC method are good options. These methods also help when the locks are stuck.
Only question I have is if the Crane tool fits TFS heads (didn't know you had TFS when it was recommended). It was designed for stock (GM) heads. I have had both Darts and AFR and modified the tool to fit but it took some work.
