No pictures yet but on the heads from the previous engine, someone had mixed the long and short bolts from the cam towers. This caused the threads to pull out. I tapped the stripped cam tower bolt holes out with a 1/4"-28 fine thread tap, bought new grade 5 bolts and all looks good. I didn't even have to pre-drill the holes, I started the tap through the cam tower to make sure it started straight, then finished them, blew and flushed the chips out and the new threads are nice and tight. If I had a bottom tap I think I could use 2- 3/4" long bolts for some more grip too.
Thanks to whoever suggested it on here a while back.
Oh I started porting them also.
