i have a set of 243's with the longer valves that i plan on putting on an lq4 6.0.

for now, just the stock cam will be used. is there a longer pushrod needed? i have searched and it appears most questions are based around the z06 cam.

any help is appreciated, thanks !

If you are positive you have the heads with the longer valves then you will need a pushrod that is .050" shorter. That would be a 7.350".

100% positive, thanks for the info. I changed my mind though and threw them up on ebay. Appreciate the response !

You have to measure with any mis-matched combo.
