Good offer, I agree with scrapping the original head. Has anybody actually done successful combustion chamber welding on alloy/aluminum cyl head? Nevermind if its warped or not. Massive problem in olden days was nobody knew how to plane cyl head surface without removing too much metal. Exceeding cyl head tolerances pushed compression through the roof and next goes wristpins and bottom end bearings.
And I was told these engine cannot be resleeved on account of tapered bores mated through intense heat/weld process to original thick high nickel content "sleeves" that more closely resembled cores. It aint like yer gonna be able to knock out the originals with a hammer. Probly gently hone/resurface scored surfaces instead. Then use original pistons and soft metal replacement rings. Piston slap is unheard of among m180's. And hieroglyph markings on each piston refer to weight and size, exactly ballanced to match the crank. Dont let any of the parts get mixed up.
I think less is better than more when it comes to working on m180 sortblock. If it was me: I'd gently hone existing bores, install new rings, get 2nd hand cylinder head, valve job guides and seals - thats all.
