bought an ls head from a member..had a little work done..but he said the valves need to be seated because well heres what he wrote:

i got it from a guy and he said that the vavles need to be seated so i told him get them seated and i will buy the head so he said it was done put the motor together and low compression so took it apart could see were it was wet around the some of the vavles but i just think they need to be seated i have no more use for the head im doing a b16 but the head is p&p 3 ang vavles job new vavle seals and guides lmk tahnsk

now i poured a bit of denatured alchohol in the ports..and a small amount leaked from the valves..now after reading around i figured that the valves will seat on their own and ill just have to drive around and let them seat...anyone else have any advice..answers etc?

thanks
