Now that i have the correct cc head my compression is up at 9.83 to 1 like i original wanted, not 9 to 1. Also the flow chambers are way bigger and the valves are huge compared to the old ones. The exhaust valve on the new heads are almost the same size as the intakes on my old heads, thats funny. i am going to drive it tomarrow as long as it is not raining, i don't want to take it on the first drive when its wet cuz i want to see if runs stronger and not just spin the tires. I'll let you know and maybe if it's nice tomarrow i'll cruz up. Posts: 161 | From: Petaluma | Registered: Dec 2005  |  : silverLX ¯ Member # 3207 posted                              Congrats. Bring it up sometime soon -------------------- 88LX hatch 410w 88LX vert gears, exhaust 95GT H/C/I Posts: 1613 | From: Sonoma County | Registered: Aug 2003  |  :
