there already on the car as im using the 317s that came off of it for my turbo build. it actually put down some really nice numbers with a catback and a tune so i would say that 241 are not as bad as people make them out be but 243 would be better, but it put down 368 rwhp and 374 rwtq in its current setup with 241s and a stock cam and those are sae corrected as soon as i get my camera back ill take pics and upload them for the nay sayers that will undoubtly follow. and this not a shot at you merv iv gained great info off you i just read back through this and edited this cause i can see how this could be takein that way, just for the record.

Can someone calculate my CR on the LQ9 with the 243 heads and cometic .06 head gasket? 317s milled to 68cc with a .04 cometic gasket may work nice as well.
