big bore domes

[lee37vernon]

can you actually buy big bore pro design cool head domes or are they all specially cut . ? i cant find one place that lists anything bigger than 22 cc .

i have a 28cc that i want to keep in case i later want run race gas for the cool head and i have a pro x head with a 32.5 cc dome for pump gas .
but i want to try mixing 20% toluene into my super gas to get 97.2 pon first .

I thought that you could run 21cc on pump gas and anything smaller like 20cc or 19cc requires race fuel??
