i am replacing the heads on my dads, '95 4 runner v6. i had a mishap and the cam gears rotated before i had a chance to set the #1 piston to top dead center when tearing everything down. i have the piston at tdc now and the cams are aligned with the timing marks. i need to know if there is a way to be sure that the piston is coming up on the compression stroke. does it matter since the cams are not attached with the timing belt? as long as #1 is at tdc can i go ahead and install the belt with the cams aligned with the marks and be ok.
