Compression Release for a Kicker

I'm building a 84 in. 58 Pan/Shovel engine, it's got 9.5:1 pistons and "B" Andrews solid lifter cam. I've got the heads drilled for duel plugs, but I was thing about installing compression releases. It's kick start and I'm 75, I'd like to lighten the kick a little and still have the power of higher compression. I remember back in the day some of the big one-lungers had compression releases. Anyone have any thoughts on this..!

No input, but it brings back memories of one of my high school buddy trying to start his 441 BSA

AV&V sells manual releases. they sell a lot of hd parts as i run the top end valving/guides from them, quality parts.
if you do not mind positioning the engine, you can get by with just one release allowing the flywheel momentum to carry through.

i was under the impression he was going to run dual plugs. yes, the v&v will have to have their own hole but then again, always convert one plug hole.
