Ok everyone. Just finished up the swap and everything ended up working out well. Went with a 7.425" pushrod which came out to a pretty consistent 1/8" preload across the board. Cranked 'er up and she sounds as quiet as before. No noticible valve train noises whatsoever so I am pleased. Drove it around the block and all seems well. Open long tube headers is way too loud to drive much though. Will be getting exhaust installed by end of week. If I can come up with a FAST intake pretty soon, I'll throw that on before I hit LG up for a tune update and new dyno numbers. Thanks again to everyone who guided me through the pushrod/valve spring problems.

Update:
Here's a picture of the new exhaust being fabbed up.... It sounds great with the cutout open. Not so great when it's going through the stock catback (very quiet though =) ).
Waiting on my 255 fuel pump to come in so I can install it and the upgrade fuel pump harness. Should be back on the dyno pretty soon to get the exhaust/rocker arm/spring change numbers and see if the tune needs any tweaking....
