I got them from Gunner at patriot performance for 450 assembled. I can get you his phone number if you want it.
Or wait did you want know where i got my 243's i am trying to sell the 241's but i forgot that i cant post in the classified section on this site.
Off my car, I put 243's on it since i had the heads off anyway. The car ran great till the head gasket went as soon as i realized there was a problem i stopped driving the car.
where did you get the heads ?
