Ported LS1 cylinder heads FS
Hey guys we have a few sets of LS1 heads for sale. We have some results from some very mild heads that we ported on an A-B test fully optimized tuning before and after.
there was some issues with the tach lead on the dyno pulls but I wanted to show both w/ TQ and w/o bc the other cut off short into the max RPM band
These heads have been milled -.025 and have had a 3 angle valve job.
The heads should be close to about 11:1 CR which will raise the all around TQ and response throughout the RPM band. These are a typical port job that we do. We fully open up the intake and Exhaust port removing the areas of restriction and turbulence. The Combustion chamber has been finessed to unshroud the valves and pick up mid lift flow. Our goal is best all around Torque. We are after a port that flows the highest velocity, the higher the avg air speed the better it will fill the cylinder throughout the RPM band. Anyone can make a big port to make a lg flow number the problem is it kills the TQ like many of the heads out there available for some pretty big sellers. We have shown the areas that we reshape to optimize flow. The difference is evident in the pics vs stk, but the actual feel of the ports is very different in the subtle areas when you run your finger through the ports.
We are merely offering a budget cylinder head that will deliver the power that we conservatively claim.
Please give me a call if you guys are interested 813-495-8778. Without springs exchange $750.00. outright add $150, with new Dual springs Ti retainers seats and seals add $300 assembled. If springs provided $50 to assemble. We can install them, price will vary upon the vehicle.
Thank you
