    As the title says. I have a 67 Riv 430 in the machine shop and the block is done, but they found multiple cracks in the heads during magnaflux. My casting number is 1382985, but any big port head will work. Will also consider converting to later 455 heads if I can get a big valve stage one head.

    I’ve got a mildly ported small valve 455 head set for sale shortly, just thought I’d mention it.

    I could definitely be interested in those. Who did the port work? Any flow numbers? Any other machine work?

    I have a set of 455 heads. Factory big valve off a 71 Riviera GS. They flow 240 intake and about 200 exhaust. Less than 1000 miles. New springs were installed and valve job done same time as port work. $950 obo. I’m in Quincy,Illinois 074BAA99-7492-4785-AA80-6B53E35DBB09.jpeg

    I have a set of tall port heads from a 1967 Electra 225.
    They were MPI and found crack free. (I went with TA ST2 SE heads on my build)

    Bare castings only. Dissasembled, and tested. No other work has been done to them.

    I am in Florida panhandle.

    I'll wait at the end of the line behind other considerations and offers already posted.

    Of big port heads that is, that felt weird to type!
    Ouch, just saw your location... but if you're up for a 3,ooo mile road trip?!
