on some import heads they are so difficult to remove you have to kill the seal with a torch in order to yank them off.

from who? in what decade?

anybody have an extra one collecting dust?

pressure test the head. I bet the crack through the seat goes nowhere.

Iron blocks usually clean up with .005 or less unless it was absolutely cooked at some point in it's life.

unless a max effort racing engine, chasing 0 deck height by means of decking isn't the way to go.

can I run a moly top ring in a low boost application without worrying too much about the moly getting knocked out of the face of the ring? If the thing starts rattling and the guy driving it can't hear a thing because the external wastegate is screaming straight to atmosphere, is the engine going to...

would lover to hear that thing at full song knight! you wouldn't happen to have any pictures of the crankshaft would you? didn't know SR had two different style crankshafts. Just what you can see here, didn't take any before fitting it. 20231206_122756.jpg so it's a "semi" counterweight c...

Most companies will tel you that there is no need but, I re-torque them anyway.

does this go for any HG type/composition in any high performance deal?

I make my own broaching slugs in my lathe. They are huge time savers and do not remove the coating off cam bearings.Way better than scraping. steel or aluminum? the raised rounded "bump" in the center of the broach.....001" proud of the of the camshafts journal diameter, or greater?

it is tight from a stack up of tolerances.

sometimes they slide right in, sometimes they don't.

It will either seal up or it won't.

a composite graphite style gasket is going to be more tolerant to a less than perfect deck surface.

MLS headgasket sealing 101.

are there commercially available, adjustable cam bearing "broach" tools available to the engine building world? got some snug coated cam bearings in a LS vortec I am trying to sort right now. I would scrape the bearing if it were not coated. I can polish a few tenths off the cam as well, b...

thanks fellas!

will get a set of fel-pro shim style gaskets ordered tomorrow and have this thing buttoned up in short order.

The flatness of the cylinder head is the critical factor as long as the block decks are clean. if it takes say .005 to get the deck of the block true, (and I skip that step) how is that .018" shimstock gasket going to have any chance of long term survival? the heads have already been decked, h...
