Topics one should cover in a "new head" walkthrough video
Over the holidays I'm going to put the new Winfield head on and I was thinking it might be good to make a video walkthrough. Installing a new HC head on a block with the engine in the car is a fairly common task and something a lot of new owners might be contemplating.
I looked at the YouTube videos that cover head installation and they're not great, a lot of "personal choices" that some might quibble with, plus they tend to skip a lot of important checklist items. So with that in mind, what topics should a "new head installation" video cover? Things I am NOT going to cover:

Anything else I should draw attention to as I go? |

Re: Topics one should cover in a "new head" walkthrough video
Other topics?
Which head gasket should you use. Correct tap for chasing threads. Piston to head clearance. Best way to seal water outlet to head. Regular studs or grade eight studs. What torque spec to use for head nuts. Don't mention motor oil, you will already be in enough trouble. |

Re: Topics one should cover in a "new head" walkthrough video
Which head gasket should you use
I'll cover this briefly, I'm following the Yapp standard of Graphtite. But the steps are all identical if you're using copper, so I don't think it's worth stating a preference. Correct tap for chasing threads. Noted Piston to head clearance. I hadn't thought of this, I guess I could cover that under the warpage/valve damage section. Best way to seal water outlet to head. Covering that, I'm gonna use Permatex Ultra Black. Regular studs or grade eight studs. I'll discuss the studs I'm using, but again, I don't want to state a preference because the procedure is the same. What torque spec to use for head nuts. Covering that. |

I followed Dave in MN's advice and didn't use antifreeze for 500 miles or so and my head doesn't weep.

Re: Topics one should cover in a "new head" walkthrough video
You already have some great ideas for the video.
1) Do you paint the head before installing so you don't have to paint around the nuts? 2) Do you paint around the edge where rust normally forms between the block and the head? 3) Anti-seize compound on the treads!! |

Anti-seize: Fallucca doesn't use it (he uses RTV), but if I depart from his standard it'll be here. We'll see. Nobody explain to me about anti-seize, I have read all the posts. |

Re: Topics one should cover in a "new head" walkthrough video
Just finished putting a 6:1 head today. Had alot of help from a couple of FB's. and Snyders. Distributor wouldn't fit easily in hole on new head. Had to use emery cloth for several minutes on the lower distributor casting (even on my spare distributor). Distributor index hole would not accept the distributor index pin. Had to clean paint out of the hole and file down the pin. Sure is peppy.

Good time to look at the water jacket behind #4?

Re: Topics one should cover in a "new head" walkthrough video
I think I'll suggest in the video that you inspect the water jacket behind #4 and wherever it's visible to get a sense of how bad your deposits are so that you can follow up the new head with a cooling system treatment. I wouldn't want someone to halt the operation unless it was really really bad.
Good idea, thanks. |

Re: Topics one should cover in a "new head" walkthrough video
If you are going to use a gasket under the water outlet don't flatten it, if you are not going to use a gasket it has to be flat----

Re: Topics one should cover in a "new head" walkthrough video
Gonna go the Permatex silicone route, so it needs to be flat. I planned to test flatness with Prussian Blue – it's a good opportunity to demo this if folks haven't seen it before.

Yes, I would like to see your video and what to do with Prussian Blue.

Re: Topics one should cover in a "new head" walkthrough video
Lap the outlet on 320 wet or dry paper on glass, no need for Prussian Blue...... Lapping work it in a figure 8 !

Re: Topics one should cover in a "new head" walkthrough video
Piston to head clearance is called 'quench' ideal .040. measure piston protrusion before installing head. Crushed copper gasket right around .070.Squeezing the fuel air mixture tighter increases efficiency and reduces the tolerance of improper timing the stock engine compression ratio has. Spark knock has a greater hammer effect on main bearings with increased compression .It should be avoided at all costs, which is why a lot of folks use a mechanical advance distributor with higher compression (6to 1 and up).
Compression increase is a real power producer, you will feel it right off the bat. Add fuel to maximize the increased compression return. The stock zenith flows at about half of the engines capable air flow. know as Cubic Feet per Minute, or CFM the stock A engine flows at roughly 160CFM,the A zenith at about 80CFM..The weber carb available from the vendors flows at 160CFM.Matching air flow insures a full charge of fuel/air to the higher compression head, yielding the most efficient power the engine can make with the cam it has. |
