Sbc 408 small chamber heads for more compression
I am considering changing cylinder heads from the current 64cc chambered 200 cc Sportsman 2's to 50cc chambered 220 cc heads from engine quest.
The engine is a 408 sbc, 11.7-1 compression, 250 duration at .05/.575 lift on a 106 lsa. The intake is a edelbrock dual quad. The fuel is E-85.
Would there be a worth while gain in output for the above combo?
