When we sell the old house... ill be looking for a new rear end assembly, and new n/a power. Been thinking of heads and rockers and some fuel delivery stuff maybe.. shrugs. Damn the slow realestate market.!!!
Nice work
Thanks.

Well, since I milled the heads/had Tony port the intake, I have been going to the dyno after each mod. I think it is really cool to be able to see what your money is doing 
Between the clutch, headers, and now this, I have gained 31 hp and 24 ft-lbs in the last month. Getting the right parts to work together is key (Thankfully, Tony helped guide me through these things and opened my mind to things I never thought of).
good luck selling the house

No problem guys, I wanted to see this kind of stuff myself and figured since no one else had it, I might as well do it haha
I did not modify the valve covers at all. I also ran them for some time and pulled the covers to check for wear, and saw nothing on the driver side (didn't want to fool with the passenger side lol).

Nice ! We have more in stock for those of you looking to pick some up , you can order them here www.neweraperformanceparts.com . We made 845 rwhp with these rockers reving to 7200 rpms with a huge cam (257/265 .650/.650 112 lsa) with no issues .

i just put these in as well. i did it more for reliability since i shift at around 6900. i did not realy notice any increase in power, but the throttle response did seem a bit better. great numbers and great mod.

I have the TSP stage 1 ported LS6 heads with stock-sized manley valves and hardened stock-length pushrods. I'm running the .660 lift PRC dual springs if that matters at all
