[TRADERMIKE 2012]

Like many before me, you have rebuilt your Engines and now it is my turn to remove the Heads, at last, I have always wondered what they look like?

With the Heads removed it turns out that they may have been removed in the past because it appears that the Pontiac mod. to the water jackets have been initiated. At first glance the water jackets between the center exhaust jackets have been filled in, however, I don't see the front Head or Block ones filled in to have the water enter to the rear of the Heads. I have read the way to perform this mod., I just have to dig around my archive's to find the forum member who coached me on this in the past. I do Intend on sending these Heads out to be repaired. From what I can see it uses the 10.75 cr 428 HO type pistons. The Exhaust valves do not contain Hardened seats and some are flush to the Head and some are not, one is below flush, so it is good that I decided to plunge into this motor at this time.

First, I must purchase the degree wheel that I was told to get and I need to buy the gasket set to put the Engine back together. I want to change the Valves to the modern ones. As far as the springs are concerned, since they appear to work fine, I would like to at least shim them to even spring pressure and will ask the shop to do so. I will ask the cost to Port the Heads to the Intake Manifold. I don't think Porting the runners is necessary for a street Vehicle like mine is. I plan on using the original Rockers for now, trying to get as much out of the bottom end of this original Engine. All at the bottom end looks well and has always been strong there too.

Work done to this 1967 428 ci HO motor over the past 10 years and less than 10 k miles since I owned it is this: New 041 Cam, Johnson Lifters, Adjustable Timing Chain and Gears, HD Chrome moly Pushrods, oil pump, oil pan, Drip rails under the Valve covers, Rebuilt Tri-power Carbs., MSD Ignition, Electronic Distributor, HD Rocker shaft studs, and a recently rebuilt TH 400 by yours truly. I have some photos to share and any input on the topic is welcome, thank you in advance, Mike out. P.S. I will be measuring the Cylinders at the top, middle and bottom next, so far, the cylinder walls look un- scratched.
