Oops! Forgive my previous post as I didn't fully realize what motor you were working on.
You're might really taking a chance on bending a valve here. Without aligning timing marks up PRIOR to timing belt removal. What's done is done now, so compress the tensioner spring, pin it and put it back on the engine. Then put the new belt on with all the slack where the tensioner hangs and pull the pin to tighten the belt. Then rotate the engine BY HAND...use a ratchet NOT the starter! Yank the plugs if it's too hard to turn. Rotate around to timing marks and make sure everything aligns before running. Crank to cam ratio is 2:1 so you may have to rotate the engine twice for all marks to align. If the marks are off a tooth or more do the belt removal again and align all marks prior to belt install.
