Couple more pics. I pulled one intake and one exhaust valve and measured guide clearance. .0015" on the intake, .0017" on the exhaust. I'm happy with that. Checked installed height and was satisfied with that as well.

What are you doing PCM-wise for the first round of upgrades?

According to Raylar, with the HO ECM I can just raise my base fuel pressure to 51 and that is all that is needed. I don't really love that idea because now I am running an additional 8 psi of fuel pressure at idle, surely that is going to richen things up. I called Whipple, but that call really didn't get me anywhere, I am pretty sure I was talking to somebody who was just willing to sell me a canned stage 2 tune. I don't really want that either. I tried to explain that but didn't get very far. I want to keep my stock rev limiter and I don't want to only run 91 octane either. What I want is a calibration that is optimized for the Raylar heads and cam, that maybe tweaks timing for the better heads but still allows me to run 89 octane. Next time I talk to Raylar I am going to see if they have somebody better to talk to at Whipple than whoever it was I was talking to.

51psi sounds kind of high I think I am at 46 (I cant remember though). Keep in mind you will be close to 10 to 1 so running 89 will be tight but might be possible. The whipple stage 2 may allow you to run 89. I have been running 89 dock fuel for 2 years. I have a custom whipple HO 600 program that i assume is a stge 2 or more.
Mine have never pinged.
What headers will you be running? An O2 sensor might be in your future....

And the heads I have are the full CNC ported heads, not the extreme ported version they have, as that is really overkill for what i am doing.
This year I am running the stock exhaust but will be extending the risers about 12 inches. Next year it is a toss up between the CMI sport tubes or the Dana flow torque exhaust. I have plenty of time to decide.
