Looks like the only mods you could fit in there would be to open up the exhaust port , channel and port match it with you're header , maybe room to get a auxiliary exhaust ports , transfers i would not touch besides mild reshaping with a file for symmetry , but if you were able to dig a couple pockets into the bore between the transfers without breaching into cylinder studs , and add precisely timed charging holes into the piston , youd have some boost ports . Modifying the combustion zone and getting more compression and a squish would help too. I still dont know why people think spray on copper is a suitable head gasket , the reason you have a seal is because youre head is aluminum and the cylinder is iron .
