Some have recessed bolts some not, I wanted to go with the Fel-pro because of the 3-rib design, but not sure if recessed bolts pose a problem. Is this okay?

Another tip. Most times you remove stubborn bolts with heat, you heat the material around the threads. I once broke an Allen wrench in a retainer plate flat head screw!! I didn't want to try heating all that aluminum around the screw threads, so I put the flame right on the screw head. You're basically trying to liquefy the loctite in the threads. It only takes about 6-10 seconds, and it will come right out. BTW, in my apprenticeship, and also from journeyman Tool and Diemakers, we were taught not to use any threadlocker on countersunk holes/flathead screws. Maybe thats why I broke my wrench!!! Still, I can't recommend foregoing loctite in this application, it's just extra insurance. Hope this helps.......![Mr. Cool](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_cool.gif)

So if I need to use the Trick Flow dampener adapter(not sure if my block is drilled for it yet) I would probably want to use the flat, non-countersunk plate?

Amazon has the mahle ls1 thrust plate or cam retainer plate new for 13$-15$. I bought one for my 99 corvette ls1 cam swap. Brand new factory style plate with the flat bolt heads not the new style countersunk i had a countersunk plate one time and seemed like it would crack at the beveled part of the plate bolt surface area.
This is the flat style prior to 06 worked great for my 99 cam swap its currently 18$ was 15$ when i bought one and went down to 13$ right after on amazon summit has it for 15$.

Question: Is there a clearance concern between the countersunk vs flat bolthead approach. I have 5.3L engine. While torquing the countersunk plate the bottom hole cracked. Not a good feeling!
My question/concern is if I go with the flat boltheads is there sufficient clearance between the top of the bolthead and the timing gear that spins around above the bolt heads. It appears as if there is, but GM must have had a reason to go with the countersunk style.

I’ve never had a clearance issue while using the plate with outside bolt heads.
