Re: Question of the day? 307sb, timing chain and valves

Is it a stock motor or has the block been decked or heads milled or anything like that? If it is a stock type motor pretty good chance you didn't hurt the valves. If it a higher compression and parts have been modified for less clearance there is a possibility that you hurt them . I would at the very least do a leakdown test on the cylinders. But would be better off pulling the heads and actually looking at the valves and checking them out. Hth Dan.
