241s to stock 243s.... worth it?
Is it worth the time to swap my 241s to 243s? I have an MS3 cam right now in it will I have any issues with clearances? An I'm getting them for 400$ an only have 27k on them... I plan on porting an polishing them while they r off the car.. Any HP/tq #s would be nice or track times

stock 243's over stock 241's all day long. its a better flowing casting. a touch up on the tune will get the most power out of the swap. any internal engine mods should be followed up with a quality tune asap.

243 heads
you can at times pick up some power using the 243's over the 241 heads

243's win majority of the time when compared to 241's.
