Gen 3 heads that have been fully ported. These are off of a 3400
Gasket matched, bowl work, modified combustion chambers, unshrouded valves
Basically these heads have had the works done to them. I did all the work myself with professional tools. I spent a lot of time on these heads. The plan was to use them on a fiero swap but the Combustion chambers are still a smidge too small for my dished pistons and compression would still be a tad higher then I want.
The little ridges in the chambers by the valves and been removed and the material has been blended into the chamber. This helps to unshroud the valves at very low lifts.
The nubbin next to the spark plug has been removed as well and smoothed for no sharp edges.
Chambers have had the valve divider smoothed and rounded instead of coming to a point like stock
Combustion chambers have recieved a full polish as well with a 180 grit wheel
Intake side the ports were gasket matched and bowl blended. All casting flaws have been removed and smoothed. Finished with a 300 grit wheel to keep teh surface slightly rough. Short side radius has been blended and smoothed into the seat.
Exh side has had the exh ports ever so slightly enlarged. Bowls have been blended and the short side radius blended into the seat. Finished with a 180 grit wheel for a mirror shine.
Serious buyers only please. I am looking to get in the range of $325 for these. This will also include the Gen 3 full roller rockers.
A port job like this would probably cost hundreds more. I was going to use these so I paid a lot of attention to detail. Many hours were spent on these heads. Compare to other people here selling ported heads and you will probably pay more and get considerably less.
Reason for selling? Want money for other more important projects while I wait for the larger CC of the 3900 heads
