Hi all, ive recently rebuilt my vecy 2.2 sri after having to replace valve stem seals due to oil usage, ive now all most done and i am ready to set crank and put cams bk in and time it up. how ever i had some problems witht he cam bearing bolts i put one cam back in and 3 of the bolts snapped and 2 stipped the thread so as i precaution i drilled and tapped each hole and helicoiled it. my question is will this be strong enough to hld the cams? i dont want to risk putting them in and then the bolts or threads failing. any advice would be appriciated
