Heads

Thanks for that thought I lost out on the X heads the guy doesn't want the trouble of shipping even though I offered an extra 100.00 for the heads to get him to ship. The only heads are the ones that have the part #2658920-5 that I'm told were on 273 motors I can buy those for 250.00 but if my 73 heads with a little work will work better I would like to know what you all think. I don't nor want to go aluminium .
