I wanted a solid unique motor and I seem to have got that. Idles really smooth and made not bad numbers through the cats. I'm pretty happy so far, but it does drink a litttle more fuel these days.

I have two reasons for wanting aftermarket heads Brett:
1) My 6.0's had to be repaired the last time they were off
2) I want best clamping/deck setup for FI.
Last time out I hooked a 1.45 (1.49 on my 9.61 pass) on year old slicks at a track rental where I was the only one on slicks. Next time I'm out I will be on 28W's and the track will be prepped. But I don't make enough power for 8's.

For me to switch to Jesels I need custom valve covers, different pushrods, and I might have to relocate my coil packs. Sounds like little stuff but for my build I tried to avoid $900 rockers since my idea behind the build was to use readily accessible bolt-in parts to take a 13.5 car to 8.99. I'm at mid 9's now and none of the stuff I'm using is exotic.

I still don't see the need for heads on your setup, I would think getting the thing to launch and down the track would be better money spent getting another 3/4 a sec out of your car. Heads aren't going to do a huge amount on a blower car. I'd go talk to Billingsley instead.
Craig, Do the Jesel rockers require any shimming to get them to a set height with your standard valves? I would imagine the whole setup would bolt right in without too much work since it was designed specifically for your castings.

Do we just have to use a Standard C5R rocker Arm or do we need to buy custom Rocker Arm's from you guys?

Also, has the rocker cover rail been raised to allow stock valve covers to be used with shaft rockers?
