You sealed the case up without doing any of your rocker geometry, or cylinder head fitting?

Whats going to happen to your cam break-in lube when you need to turn the engine over 40-50+ times while doing the rocker geometry?

Oops.
Thereís my newbie mistake I guess. I thought I needed the case/bottom end tied up before measuring for heads and comp ratio?
So I shouldíve put it together but without sealant? I guess thatís not detrimental and can be undone.
I havenít purchased the heads yet-thought that was one of the last things to buy.?

I always make sure to mock everything up 100% before any sealer goes on.
All the way out to the valve covers. Carb linkage, tin, header etc. Once everything is good, then tear it all down and final clean everything and assemble it for good in one shot.

Then all of your assembly lubes will stay where you want them, there is way less chance of crap getting into the engine, etc.

The final assembly always goes together very smooth since you know everything fits together. No surprises to work around.

This is even more important on strokers where the case can't be 100% checked for clearance till the cylinders are on and torqued down.

Good eye! Iím pretty sure it is flat because as I was spreading the Curil everything was flat because I ran my fingernail over the edges.
Brian can you point me to a good article on setting up rocker geometry? Honestly I thought that was done once you bought your heads and measured comp ratio?
Duh...

I don't remember, but have you measured and dialed in your deck height yet?

Once your deck height is .040-.045" you can order your heads, and have them cut to get the compression right where you want it.
Once the heads show up, pull the valve springs off the #1 cylinder and install some light checking springs. Now you can start your rocker geometery.

I don't know of any good articles. I will be doing rocker geometery on an engine here in the next couple weeks. I might have to take a bunch of pics and just do a write up on it. I have a real simple method using an angle finder on your phone.
