The pro-filer heads calls for a fel pro 1014 head gasket per pro-filer.This gasket has 4.200 bore to un-shroud the combustion chamber.If you have found a thinner gasket please post it.The only gasket I have seen thinner than the cometic .027 is a copper one.
I'm a believer in compression and your afr heads are aluminum so they are more forgiving than cast iron. At worst case scenario you'll have to add a little octane boost if you get a crappy tank of gas. It happens to me with my SS Silverado with an LQ9
I have a 406 on the engine stand and I did use ARP stud for the 2 bolt mains. Your engine is very strong but I would stay away from holding it over 6500rpm for long periods of time.
Do you have a high volume oil pump?
Do believe its a stock oil pump, am building off a used shortblock I had built years ago. It was awesome at the time, but destroyed truck it was in. Resurrecting it again with some serious upgrades, hopefully my vette doesn't have the same fate...
I backed out on AFR heads, went with 70cc profilers. Still be running high comp, but should be ok.
Need help, somewhere along the way I bought a cam that I thought was close to what we'd discussed. It's a lunati #20120712 282/290 adv. 231/239 @ 0.050. 0.535/0.550 w/1.5 rocker. Says intake closing point is 41.5 ABDC. My math says this puts me @ about 9.4DCR. If so, it's no good, right? I believe I need to be mid 60's ABDC, right? Help! Do I need a different cam. Where did I go wrong?

I had this same issue with Lunati cam specs. They list all the open/close points @ .050" lift. I don't remember the conversion right now Mako63 has it posted. Try a search.
Go here and put in your specs minus the intake closing point and it will give you the intake closing.

Ok, so I reran it in jeep strokers, after I used mako's math (which I'd already studied). All good now, closing pt of 67*. DCR @ 8.13.
I was under the impression that the cam card was the "official document" so I reran it in the stroker calc and came out @ 9.54 DCR, was almost sick in my stomach, since I'd already installed the cam.
Ok, so I feel quite relieved now. Gasket kit is in the mail, should have base pan and timing cover sealed up this week. Pushrod checker is on its way too. Will be needing some guidance when I tackle this part, just have never done it.
So, leave the cam straight up and seal it up.? I trust you fellas calculations. Just want to make sure I'm not "lost in the woods" here.
