Ghostrider has it right. The only head that will get you a compression increase is the 194. The 194 has a 62 vs 72-78cc combustion chamber. That's before any valve or porting work is done. The 194 head will up your compression by about a point, your mileage may vary. Check inliners.org for head casting numbers.
