Lookin good, can't wait to strap on some 243s. If it's not too late in the process, get an 04+ LS6 Valley Cover with the internal PCV. You can cap off and remove your old PCV hoses. I have seen a GREAT reduction in oil consumption since installing mine..

I have a feeling you will be closer to 400hp with those heads/cam. I have a similar 230/230 cam with stock 243 heads, the Torque is great mid-range, right where you need it. Are you swapping out for an LS6 intake as well. Thats another 10hp right there and a quick swap since the LS1 is off right now.
Here is a great link I used for the first time I went to start the car up after my H/C swap....see post #10......

To the OP, that cam is not junk. There are people running high 10's with that cam.
I would suggest seeing if you could mill the heads to get some more compression. If you have to flycut the pistons then it wouldn't be worth it IMO.
I had to flycut my pistons anyway so I had my 5.3 heads cut to 59cc.

Only if you are a shop. I think the average Joe can do whatever.

All that's left is the radiator, AC condenser, headers and y pipe. Should finished it all up in about 2 hours on thursday.
Just so everyone knows, to check the push rod length, I colored the center of the top of 2 springs (next to each other) with a sharpie and tightened them all down to 22 ft-lbs and spun the motor over by hand 3 times then loosened it.
If the line that is made is too close to the edge of the circle on the motor side, the push rods are too short. If its on the outer edge away from the motor, they're too long. Mine was almost directly in the center. I used 7.4 hardened (not chromoly because it's a manual) and the heads were milled .020

im def not an expert, but, doesnt that only tell you if your rockers need to be shimmed ?
i thought pushrod length was determined once the rockers are shimmed correctly, then with a solid lifter and a comp pushrod checker you get the length, then you add .50 or whatever preload you want.
