So Matt and Mr. Rombyer, will 67cc chamber have any PTV clearance issues with the G6X3 cam?

LOL...my names Troy...I just used my last name so he could find my order info.

I am having the shop check obviously...but if the heads provide another .040 of intake valve clearance I cant see why it would be a problem. We will see...

I am also using cometic .040 gaskets. Should still leave me with another ~.022 compared to a stock head and gasket set up. (lost .011 from the gaskets and .007 from the mill to 67cc)

Id like to see some engine dyno results from YOU guys. I'm itching to do a heads/cam upgrade to my 10 SS. it would be nice for a before and after on a stock ls3, then add a cam.

I've been considering switching to cathedral port afr 230s, but I still haven't made up my mind. Nobodys posted any results.

What is the deck thickness on these? And when are you all expected to come out with the larger runner version?

Yes sir, we supply a billet pedestal with them so you can use stock GM (or trunion upgraded) rockers!

Unfortunately, we're still a couple months out on the larger runner version.

Took about a month to get mine from the day I placed my order. But I am not sure if they are getting more behind or catching up...so it could be more or less for you depending on when you order. Not sure if they offer any more valve options...but the standard is manley stainless in stock size (2.165/1.60 I believe)

If anyone cares Ill be getting mine next week on Thursday. I suppose I could post some pics.

I was going to wait until late March to have the heads and cam installed but the weather has been so warm that if it continues ill go in as soon as possible. I could possibly have some numbers this month. We will see. Ill be posting the results asap.
