Hurry with the intake!
I swapped the heads plus a cam a couple of weekends a go and also fitted a used ATI damper. I hadn't thought that much about pinning the crank but one of your other posts and got me thinking.
I am hoping to get the intake made this next week 
Almost seams silly not to pin the crank whilst it's off.
You driven the car since the heads and can swap? What spec you go for?
My pulley is on now so I'm going to mark the bolt and pulley for location and check it.
I was waiting for 243 heads to come up and some did on the HSV/Monaro forum. Bought them and spent the next 2-3 weeks porting them at home. I'd already bought a low mileage Comp Cams kit from Craig including a 222/224 566/568 112 cam, dual springs, push rods. Also had the ATI pulley and LS7 lifters tucked away waiting for the right day.
So far I've only driven it a few times but the impression is that the engine revs better without the heavy cast crank pulley and feels smoother to me anyway. As for power well I've gained another 1000 RPM as it's still making power right up to 7K! my exhaust is restricting any actual gains in peak numbers until I change it (I can compare airflow numbers in the EFI Live software).
