Clean pr of Mopar 3418915 J-heads w/the 2.02 int valves

I have for sale a very nice, clean pair of Mopar 3418915 casting J-heads with the 2.02 intake valves. Great street heads. These heads have bronze valve guide liners, new OEM style valve seals and have been painted the Mopar Hemi-orange color. The area under both of the intake and exhaust valves has been smoothed so they don’t have that factory sharp edge thus getting better air flow. All threads have been cleaned and are perfect but there is one heli-coil installed on one of the end intake manifold bolt holes. The date codes are 0112 and 3481. In addition, a pair of new Fel Pro 8553PT head gaskets are included.

The valve springs appear to be aftermarket but I don’t know the manufacturer. Definitely not the OEM 340 red springs. I checked the valve spring pressures and with the installed height of 1.63” the pressure was 98 lbs. on the seat and at .500 lift the pressure was 298 lbs. Coil bind looked to be at 1.10” so these springs would be great for a cam lift of .480”. These heads are bolt on ready. I would like to get $375.00 for everything plus the shipping. These are heavy so the shipping will be crazy. Local pickup would be great or depending on location, I can meet part way for the cost of fuel and any tolls. I can also bring them to the PA Dutch Classic at Maple Grove in October.
