I'm asking this for a friend since I really don't know the answer to this. He bought some 243 heads from me off of a Cadillac CTS-V with the sodium filled valves. He wants to install them on his 02 Camaro SS. Will he need new pushrods or can he use his stock pushrods ? He still has the stock cam also btw.. He was told the valve length in these 243's is a little different then the stock heads valves so we just really don't know about the pushrods.

This shows the CTS-V LS6 OEM pushrod = http://paceperformance.com/i-5131693...010-steel.html

I would measure. He may also need hardened pushrods if aftermarket springs are (still) installed.
