It seems to me if someone was to build a max effort N/A high rpm build swapping in the intake valves alone could prove to gain high rpm valvetrain stability. I can not remember but I believe these intake valves go for $19 each new? might be worth it on my next head swap.

Got some results on the full set of LS1 valve and LS6 valves
LS1
INTAKE; 98.3g 99.6g 98.5g 100.8g 99.1g 99.8g 99.4g 99.2g 2.5g variance
EXHAUST; 86.3g 85.7g 86.3g 85.8g 85.2g 85.3g 85.1g 85.4g 1.2g variance
LS6
INTAKE; 74.1g 74.2g 74.8g 74.6g 74.3g 74.4g 74.6g 74.6g .7g variance
EXHAUST; 65.2g 65.2g 65.4g 65.0g 65.1g 65.2g 64.5g 65.4g .9g variance
I was really expacting the LS6 sodium valves to vary more from anything , but the stock LS1 valves were the disappointment at 100+grams ...I guess the quality of the L6 components are better then I thought

Last I remember Pace or SDPC were getting like almost $600 per set (16) for
these valves. I got really lucky back in Jan. 2011 finding a set of new take-
outs from another member for $185 shipped. About the best/cheapest way
now is to get a used set of 243 heads off a ZO6 Vette...usually around $400
