it is if you seen how small the ports were. they are '66 289 heads. i took out about 1/2 inch of material on exhaust ports and about 1/8 all around on intake ports and blended them in. they arent oversized ports but they are hell of a lot bigger than they were stock. i could still go bigger yet if i wanted.
