3.4L heads

[allmotor03gt]

does anyone know where to get a set of 3.4l heads? I have looked at milzy motorsports and 60degree v6 store, but I was looking for something better.

Something better? better then ported 3400 heads?

Do a 3500 top end swap then. 3500 LIM, Heads, Gaskets, and 3400 UIM.

Will the 3500 top end fit on the 3100 bottom??

Yes, 3400 and 3500 top ends will fit, they may take slight adjustment but they are the same family of engines.

3500 top end will fit on a 3100 but your better off doing a 3400 swap.

well since www.60degreev6.com/store has the best heads available for these motors I really dont know how you plan to get anything better.. GL with that though

No, you cannot put a 3500 top end on a 3100 unless you bore it .060 over.
