well i got my springs/retainers today, and im getting ready to install it all, so im wondering how to go about doing this without pulling the head off the block, and without the valves falling into the cylinder. i looked at some of the valve spring compressors that craftsman and snap-on make, but im not sure if and which one of those work. Please help!!!

 

You put air in the cylinder throhgh the spark plug hole. Snap-On make a compressor that is bolt-on to do it with out removing the head
