Chevy valve in J-head

Doesn’t look like you can get a 5.011 length in Summit brand…4.911 is gonna be short.
There is the rub for me in this instance and the reason I asked. The valves I have access to are the stock length Chevy ones new in box, $50 for all 16. I am aware of the benefit of the +.100 versions but this ain't them. Sounds like they might could work for a stock lift build but being .080" short of the stockers doesn't make them viable for anything more aggressive than that.
