Default piston/valve clearance question

Ok, new cam is on the way - 231/237 .598/.595 112 + 2. Heads are LS6 castings, milled .010. Stock valves. Am I going to have to be concerned with PtoV clearance?
If so - any tips on claying to check PtoV?

Thanks

Its hard to say because you can't just look at the specs and immediatley "know." There are other factors also.

A G5X2 (which is slightly bigger than that) will barely clear with unmilled heads.

I basically just wanted to know if I even had to give it a second thought. If its going to be close I'll make sure and check of course.

I personally don't think that you will have a problem...but of course the only way to be sure is to check...I have my heads milled .040, running a cam with 525 lift with 1.8 rockers which comes out to approximatelly 555 of lift. With 2.02 and 1.6 valves, and I still had over .110 of clearance...kinda a pain to check but don't worry about it...I would check it just for more information about what setups will work....I'm sure there are a lot of inquiring minds that would like to know. :p

it will take you around 2 hours to check 2 cylenders and degree in your cam its worth the time you should have .080+ on the intake and .100+ on the exhaust and yes duration is killer if you dont do it you can change high performance parts in to high performance junk

Damn Brandon......are we getting serious? On the PV....trust NO ONE! Check it yourself to be sure Depending on springs, I'd want to see .080 or so

Ryan.....looks like there's at least a couple of us after your N/A #'s title
