@Rat Bastid I’ll do no work except in the chamber to clearance the valves to de shroud should that be the case.
Also, the aluminum is crap. It doesn’t take to any welding at all.
The port floor is only smoothed and a minor widening at max.
The valves are 2.08/1.60 in titanium. They’ll stay.
I have zero idea on how much the roof can be raised. As well as how thick the spring seat is. I can check the OOTB head for a reference. In raising the roof, blending into the spring seat area would currently be a guess and the amount of material left under the spring may compromise the area depending on what’s there stock and what is left by exploiting its max potential. I’ll not do anything and gamble. It would be foolish for a rookie to take a die grinder to this head and it’s known and UNKNOWN thin areas.
In another thread, I had gotten a name for a fella that has a W5 CNC program. This will be the last head I have ported by someone else. From there, what ever it yields, I’ll just work with what I got and make the best of it.
