ok guys so I found some 806 head's while searching for 243's , still not 100 percent sure on getting heads since I have other issues but its on the table to get since I found them for what I consider a good price. used heads always make me worry though. anyways I know Ill have to have them milled .030" to get back to 61cc from the 64cc, but was wondering what yall's thoughts, opinions, and advice would be far as getting these?? and would the 7.4's work since Im still on stock cam??

heres some info they have on them
