Heads opinion

Just got a good deal on a 408 stroker. Had a 340 with x heads I was planning on putting in but now change of plans. The stroker came with standard 1.88 j heads. Originally I thought i would sell x heads with the 340 so I could get top dollar for it and just port the j heads but that doesn't appear to be cost effective. Really trying to decide if running the x heads on the stroker is worth it or if I am better to sell them with the 340 and buy another set of heads. :banghead::banghead:
