got my block back from the shop he cleaned it check for cracks found 3 between the head bolt and water port

should I fix them for my Stroker motor or leave them

still have to take it and get sonic tested and presser tested

the shop was just a small shop and old guy he good what he does to get the other test done I will have to take it 70 miles for that

I seem they had some inserts to fix the cracks in the head bolts
 
Hi Terry, above is correct, don't concern yourself with those cracks, they are considered a "non-issue"!

Thanks, Gary in N.Y.

P.S. I've only seen a handful of these blocks that weren't cracked in that location. When we assemble them here we use the #1 (hard-setting) Permatex on the bolt/stud threads. Never experienced a single drop of water there ever.
 
thanks Gary I might have to get hold of you later for a set of pistons for my motor still getting jerk around buy him
 
I called all the shops around my area nobody have the plates for testing the blocks on my flathead now what should I do
 
FYI: Speedway sells a plate kit for pressure testing flathead blocks if you are interested in buying your own.
 
I know seen it most like I will only do one maybe I can find one to rent or send my block out some place else to get check out
 
I have thought about buying one myself for a while now. I have other flatheads to eventually build, so I will be buying them at some point. Bill
 
wish there was a place buy me but not maney people build them around here were I live most sbc or bbc not maney flathead
 
I would poor boy it. Put the heads and water pumps on. Rig up some hoses and cap the ends with some freeze plugs. Tap one for pressure and give it a try. You may have leaks at the heads or pumps but if no leaks, you know the block is fine.
 
I had the same issue on my block. A guy I work with daily drives a motor he has overhauled twice and he told me I'm better off leaving them. Flatheads only make around three pounds of pressure throughout the entire cooling system. Just make sure you put a little bit of liquid teflon tape on your bolt/stud threads before installing them into the block. Also when putting on teflon tape, be sure to wipe the bottom of the bolt so none of that **** gets into your cooling system, last thing you want is chunks of that **** floating into your radiator.
