If you look carefully the heads have been glass beaded to look pretty but the seats and guides were blasted as well. Ray
Darn the secret is out! I was hoping to get them for $149....They are converted, and need to be unshrouded, and the seats reground. Happy bidding!
To install the bigger valves you have to cut the seats then to make them work correctly you have to unshroud the combustion chamber near the intake valve. On stock stage 1 heads the area around the intake is laid back away from the valve face. Without doinf this the larger valves are a wasye of time. Then you might as well do some CC work, port and polish as well.
