Built a motor with those pistons for my brother very similar to yours.
Summit 480/480 cam
.029 head gasket
ported smog heads MP SS 1.88/1.60 valves
milled heads to 62cc 9.5-1 compression
273 rockers with custom lenght Smith Brothers ball/cup pushrods
airgap/650 demon dp/1 1/2" shorty headers/manual cutouts for the track
2500 stall/904 reg gear set/3.55/QTP slicks 26.5"
93 oct pump gas
3000 lb 66 dart, 12.7, 90* humid FL day. Still needs to be tested for best shift points.
Motor will blow the street tires off at will.
How thick are the head gaskets you removed?
