$1160.00 w/o heads, but most folks opt for at least our Stage I when doing this, but our Stage III Super-Tour Head is just the ticket with those.

Put the same cylinders on my 96" with S&S 89cc heads, 58MM throttle body, 583 cams and stealth filter. Changed the exhaust from Big Shots to Fat Cat w the smaller baffle. Pulled a PCIII and had the system tuned on a TTS.
I had about 85HP/97TQ with the V&H and PCIII. When I got it tuned after the pipe change, it came in at 94HP/112TQ. Everyone that has ridden it is very impressed with the way it pulls. I had hoped for a little more HP but with that torque number, would it make that much difference? I'm very happy with the results. Tuner told me I'd have to change cams to get the HP up and I don't want to.
I need to do a complete write-up soon and include the jpgs of the dyno sheets.

I can think of three or four small changes but all are expensive relative to the gains now that the build is complete. Different cams, head work, thinner head gasket and a different baffle in the pipe.
I believe anything anyone suggests can help the OP and others who read this when they plan this work.

decent TQ will start at around 2700 with the .570`s.if your looking for TQ coming in a bit lower,you may want to look into the S&S .583`s,set them at 9.8-1
