[System]

I bought a rebuilt 1969 428 a few years back for my 70 GTO with #46 heads. I recently went to Kauffman aluminum D Ports so these are up for sale. Only 5k or so miles on them but the build is older so they likely should be gone through before using. Date codes shown in pics. They still have press in studs but have been opened up to big valves. The end exhaust ports do have the holes drilled for headers as well. Looking to get $300 for the pair. Likely too heavy to ship economically.
