You mean stock unported?
Even so, yes but since you are in Sweden and paying so much for shipping might as well do ported ones.

Thanx i know, but i´m putting the stuff in a car thats going to sweden.

Will i need to modify anything to use 243 or is everything going to fit, like hoses etc?

Everything will bolt up , they are both 243 castings so they are the same . You will gain compression from the 64cc 243's vs 67cc 241's. Intake and Exhaust port cc are larger and the combustion chamber is a more advanced design .

..And if you choose a set of 2002+ LS6 heads, you'll get the lighter and longer intake and exhaust valves, so keep that in mind (affects PR length).

Call "Summit" ask about the "Dart, Heads" best price, and I think the answer you were looking for in regards to the "value" of doing a stock to stock head swap is HELL NO!!! You wont be spending that much of a differance going with the darts and now they seem to have all the "bugs" worked out they are a real buy!!! Oh, ya,.....you MUST do something about a cam, there are more "threads" around here devoted to that mod than anything else! There is a real good reason for that fact!!!
