Default high"er" compression flathead heads.

what would be the market behind some higher compression flathead heads? i am getting into metal working again and im getting supplies together to make a gas forge and a foundry with a crucible to pour the molten metal into molds. i was having a spark of genius a few days ago, get a set of heads off a flathead and make a mold with them and custom cut some type of larger combustion chamber with a possible different design to make the gas and exhaust flow much better. my goal would be to have the compression ratio atleast 1-2.5 more than the stock head off whatever head id use. if i did this what would the interest be in them? i would obviously test them out myself first to make sure they would be ok for sale along with making sure the type of metal id use wouldnt throw off high heat warp and any other issues id run into. if anyone has any feed back on this id really like to hear it.

you know some people are ignorant to the Flathead ...but your thoughts are good ..Flatheads have an over heating problem so by increasing the compression ratio you'll add more heat .....over come the heat FIRST....come up with a cheaper ceramic coating for the exhaust port and valve then you can go to the head...the latest is to ceramic coat the chamber and exh port...more air ....big air pump..remember...later
