ive got a 2008 6.2 denali...ive got a 273Lr HR12 cam im ready to put in... id like to deck the heads between .020 and .040...trying to figure out what pushrods and springs to get. hoping someone might know? i have a set of oem gaskets i was planning on using. soo would say mill .030 with oem which i think is .051 but about ideal? then what size pushrods?

 

i have a 370 ly6 with L92 top end...the heads have been milled .025" and im running a 7.4 pushrod

 

What size is the stock 6.2 push rod? Same as GenIII 7.38?

 

You wait til the heads come back and use http://www.summitracing.com/parts/tfs-9000/overview/ there's probably a video on youtube. we have hydraulic lifters so you add a lil for when they pump up with oil

 

measure the push rods with a tool
my heads are shaved 0.035" and I run 7.275" @ 0.050" preload...
