525 Header Failure??

If need be, I would assume (since they are aluminum heads) that the holes can be drilled/tapped into the heads for the old style header or a Stainless Marine/Keith Eikert bolt patterns?? Worst case, a welder can fill the holes in the heads and drill/tap for the old bolt pattern, right??
May be a lot of work but if someone is doing a rebuild...especially if the rebuild is due to header failure..

I ran Stellings for a few years in fresh water, set up a pump that drained the pipes and sent the water overboard after I shut down. Finally said the heck with it and bought some KE's aluminum castings. 400+ hours and life is good

Mine developed a pin hole external leak also. In and of itself my understanding is that it represents a little problem. However, it is indicative of corrosion and raises the ugly spectre of internal leaking.

I had a guy that had a shop next to mine in Naples that was a excellent welder.He had moved over from Miami and just had huge pile of Stellings laying aroung to be welded all the time. I used to spend quite a bit of time with him examining failures.
Being i had just purchased a new set of Tubular headers i was very skeptical about my new purchase after seeing how many he repaired all the time.
From what i could see and from talking to him many of the problems stemmed from overheats or debri clogging the jackets and causing a hotspot . Vibration and lack of support for long heavy tailpipe -muffler combos was a problem also.From what i could see failure was just the nature of the beast.

I think with the cost of motors you stainless header owners at the beginning of each season should rig a simple pressure tester fitting and hit them with let's say 50 psi air pressure, cap the pressure and watch for leakage. Got leaks! Don't run'em until repaired! An Oz. of prevention worth a pound of cure! Seems I heard that somewhere before?
and for the gage every thing look Ok ,
Oil pressure 45-55 psi
Temp oil 220 to 230
Water temp 160
i always check my fluid level every morning
but when i check the oil dip monday morning ( after 2 day of boating ) the level raise and the oil turn very dark , and the oil smell gaz or burn oil , the only thing i have found so far is the cool collar on the port side of the motor is externaly leaking ( not torque enough ) ,
i have remove all the spark plug and found the cyl. num 3 ( port side ) , have some little drop of liquid on the electrode ( i don`t know what is it gas or water ? ) , the four front plug are more lighter brown color (1,2,3,4) , and the rear (5,6,7,8) are more chocolat brown color
tonight i going to do a compression test .....it`s possible to all the problem will come from the cool collar ?? , i am maybe just on alert mode , but it`s better to prevent than say i am sorry !!!
Ok guy sorry for my poor english , but if you can take time for me , it`s going to be very appreciated

The rise in oil level is strange.... Is it milky in color?
