243 heads valve upgrade question

Can someone tell me what "length" intake and exhaust valves should be ?

Looking to buy 2.08 intake and 1.60 exhaust valves.

Thanks for your help !

I measured a couple for you.
A bit tough to measure, but I got 4.91" from the flats on the valve face to the tip.

Thank you very much Ron !!

Now...... I'm looking to buy a set of:

COMP Cams / RHS Sportsman 2.080" / 1.60" Stainless Stainless Steel Valves.

Will there work for a daily driver ?

Sure they will. Stock valves are actually a type of stainless.

Just make sure what you are looking at have 8mm stems.

The description doesn't give stem sizes in mm...

Exhaust valve stem is .3136
Intake valve stem is .3133
