thats not true if you can get pressurized air into the cylinder (there is a hose you can get at the parts store to attach to a compressor) that will hold the valves shut in turn no need to pull the heads

Yes, you can. But the tight space it is easier. If you have to machine for the springs or studs they gotta come off.

with that kind of lift and rpm range your looking at building the bottom end. also going to need other mods like rear end and trans improvements. good cam just not so streetable. do you need to pass emissions tests? bc considering the ease of changing spark plugs attaching the air hose to the heads would be a breeze right...

yep its one thing to squeeze your arm in there to get the plug to start, another to get a hose in there. im sure it can be done. other side of it is getting the spring to compress and get the retainers in on the back cylinders. i almost went that route but getting a spring compressor that would fit in there was a challange.
