I changed setups and am unloading stock and aftermarket parts, some of which I couldn’t reuse with the 99+ cylinder heads. All of the aftermarket stuff has been in the car since 2010 for around 8,000 miles. The heads have 116,000 miles on them and showed no problems when removed. This setup made 380 rwhp and 355 rwtq on Speed Inc’s dyno through an A4 trans.
Head stuff can be sold separately or as a package deal. I’ll let all the head stuff go for $500 together; heads, rockers, spacers, springs.
$80 - Taylor 1998 aluminum valve cover spacers for roller rockers and big cams that I used with the Yella Terra rockers.
$150 - 1998 806 cylinder heads, stock. If I had the time I would have sent these off to be ported by Advanced Inductions but, alas, I did not have that flexibility. AI claims up to 35-45 hp gains with their more extreme porting options. Will come disassembled so they’re ready to ship off for porting. Valve covers come with and can include stock springs or the PRC .650 beehives listed below for a package deal.
Advanced Induction - LSX Cylinder Heads
$250 – [SOLD] Yella Terra Ultralite 1.7 Non-Adjustable aluminum rockers for cathedral port LS heads including car engines LS1/2/6 and truck engines 4.8/5.3/6.0. This is not the model that had failures, but the better, earlier model, as you can see from the 1.7 stamping on the left side and not center – or at least how it was explained to me to determine the difference between the good and bad sets.
$100 – PRC .650 beehive springs. [SOLD] All but two tested within factory spec. Speed Inc said they would be fine in a smaller cam with less than .600 lift.
$200 (SOLD) – Comp Cam LSL lobe 231/235 .617/.620 113 +3. Nice, lumpy idle that will turn heads and get thumbs up from the sound.
