YR, I have read many of your posts and am 100% NOT going HR. I said the plan is solid roller. And I was really looking forward to your response because I know you have the answers but its whether or not you decide to share.

You say is can accept a roller. Well any block can accept a roller, just depends how much money you want to throw at it right?

Ott, what points of failure are you reducing? A needle bearing exploding in your block? What other points of failure?

needle bearings
roller rockers
lifters not pumping up or failure to bleed off appropriately
lower spring pressures with flat tappets vs rollers
reduced mass in the valve train

Every moving part is a potential point of failure, granted if you use quality parts, you reduce the probability of failure but i want to completely eliminate that potential as best as I can, and I want to rest easy knowing that if I **** up somehow and I knock it out of gear and it revs up to say... 9,000 I am less likely to cause damage.

It is all about risk mitigation.
So what if I have to check and if needed adjust the valves every year.
When I rode a motorcycle, I replaced the tires every year before the rains started.
