From the pic it looks awful close. While it misses now, what about at operating temp? Feelers gauge to check for exact numbers.

Doesn't the cam naturally walk forward towards the retainer and away from the block when running? I know when I went to a roller cam and a cam button it wanted to push my timing cover off the block. I have to put a 1/4" plate between my timing cover and crossover to stabilize it. And the button wore pretty good.

You could have ground it and been done already

i would grind it, and never worry about it again.

why not use the right chain in the first place... the Gen 6 with step nose cam/retainer system is great!!! wish all BBC were this way, to run a dbl row chain you need to clearance the block... the single severe duty chain system by Cloyes (9-3649x3) made for the Gen 6 is a brute single row true roller, multiple keyway for variety of timing positions. Just my $.002

I had same set with my GMPP Gen VI block. Had to grind quite a bit. Didn't rub during assembly/mock up, but certainly did when ran!

I looked at Cloyes and looks like a fine set and cheaper too. This was about $125 with more adjustability, which I didn’t need.

Exactly. I don’t want a problem later.

Timing set for GenVI. Any favorites?

Thanks. Grinding will be done! No big deal.

I feel ya Rooster!
I've asked the same question in 2 different threads and got nothing but crickets for almost 2 weeks
Timing set for gen v block with step nose cam
Which Gen 5 double roller timing set?

I looked up your part number on roll masters product list and a CS2090 does not even come up

I have a double roller recommended by Eddie young. Had to clearance the factory timing cover but that took minutes and nowhere near the engines. Howard's 94309.
