Porting a stock 372 cylinder head is far more costly than this high quality, bolt on, over size piston and cylinder head by Hyway. It delivers outstanding torq and performance over the OEM. Hyway does recommend a 40:1 fuel/oil mix but I've used a 45:1 mix with no issues. Just make certain you have no issues with your saw before installation.
Hyway big bore kit had smooth porting, and quality casting. compression tested to 160 before startup. Running saw a little rich for break in, but still pulls 24" bar strong through 20" plus hardwood.
