I noticed Isky has bushed hyd rollers now.
They're not cheap and I haven't seen anybody mention them.

I ran isky red zone, needles, for 15 years, with 600 lbs on the street, finally had a needle fail.
The sizing on the BAMs is dead nuts 👍

Yea right. Googling about oil you end up getting different product results every time.

Amazon basics full synthetic outperformed Mobil 1 synthetic. Wonder what factory that comes from

Amazon Basics engine oil is made by Warren, who also makes most of WalMart branded oil. Take care. Tom Worthington
 
For my future reference.. the minimum piston to valve clearance on the paperwork calls for:

.080" int
.100" exh
.050" radial

Piston to head clearance for steel connecting rod is:
.040"
This measurement includes deck clearance and compressed head gasket thickness
 
Shafiroff also said to use 10w40 oil...
 
A little bit of internet searching shows the Morel 5323 lifters are rated for:

100-180lbs seat
280-380lbs open

The springs on my new heads are
145lb seat @1.8
410lb open @ 1.140

My cam won't be .660 lift, but either way I think I've ruled those out.

If you ain't at 660 lift you ain't at 400 lbs
Calculate the spring rate and interpolate what pressure may be at lift required.

Now I have to check the size of my engine. I know I have a 3.875 stroke crank and I am pretty sure it is a 4.155 bore. I thought I had a 427.
Now if your bore is 4.125 (which mine used to be) but a 4" stroke brings you up to a 427......... I thought a 4" stroke on these blocks (4.125 bore) came out to 434. Doesn't really matter......... When my engine was only a 4.125 bore with that crank it was a 414.
