New Rebuild Part Two Questions

So I'm redoing my motor again for the second time I need new bearings in the mains and the rods. First question does it matter whether their Coated or non-coated. Second Clevite or king. Or some talk about federal mogul

 

Timing chain. Stock or get a Manley dbl roller.

 

Lastly

Valve seal. Aftermarket that already failed once on my motor or go back to stockers?

Need some advise asap as I need to order parts now

OEM or Clevite bearings, definitely stock timing chain.

See which valve seals are recommended by your builder for your spring application.

 

Are you planning on honing & rering ?

yes rehone and re ring

 

when i put in the PSI 1511 springs i got the seals from modern muscle.. not sure what brand ( blue if that helps )

the little springs or retainer springs on top of the seals 2 of them have popped off.. which tells me that a. possibly they was not installed square? and b. they are leaking.

 

i would like to know why on not the manley on the timing chain? and is there issues with king bearings?

From what I've been told by several reputable builders is the manley chain is actually a bit longer and with use & wear on the tensioners you stand a good chance of valve contact with the pistons.

 

You aren't building an old school flat tappet motor, this is roller lifters, no need for a double roller chain.
