A XFI RPM HR cam is what comp specked out with
.220/.224 @ 50 and a Valve Lift of .530/.534 @ 50 on a 114 LSA.. But I'm going to ask the guy we deal with from comp at work and see what he says.
Got my block back from cleaning this morning looks pretty good wiped the cylinders down with some oil to keep them from rusting. Now time to take it into the shop and start taking measurements.
Dang went through a few of the rods and the id on 5 of them were 3,4,5 tenths over sized. You can see where the bearing was moving a bit in the photo. I was hoping this spare set I had would be good.

I haven't done these. They were a set from another block I bought a few years back. You can't resize broken cap rods anyways from what I understand.
Sure you can. You just hone them about .002" larger. All the bearing manufacturers make a bearing for the .002" oversized housing bore. You don't even need to cut the parting surface.
Went into the shop this afternoon to clean and check the spring install height and seat pressure. Got the install height 1.850, but the spring tester wasn't working for me. So I'll have to retest agian Monday. And I'm pretty sure I was not using the height gauge right. I did put the heads in a solvent bath for about an hour just to make sure they were really clean.

Pulling this thing out of the mothballs. Finally got around to checking on the valve spring install height they were damn near dead nuts 1.800. Got the guys on in the engine shop to check the spring rates while they were helping just to see for kicks a giggles.
Went into the shop this morning and ported and shimmed my oil pump. Amazing what a few minutes of work can do for the entrance and exit of it. Rods came in yesterday and bought a set of pushrods to go with the cam I've finally settled on. 227/235 @ .050 .614/.621 lift on 113
Started weighing the rotating assembly today. Forgot to take pictures while I was doing it. Ordering bearings in the morning, and hope to have the cam ordered Monday. Only a few other things to order!
