Can you convert a set of originals to B1 MC's
I thought they were from the same castings.
What's entailed or is the valve angle the problem?

They start life as the same casting.. but when they make the
M/C head they move the valve over.. so the guide is moved over

You can do anything want with them if you are willing to spend enough money, but why would you? Why not just buy new castings or an MC setup?

You can but you will have to have custom guides with oversize od's made to move the guides over.

Wrong Mike, we flow tested your heads and they were 418 @.900 with a 2.400 valve and a 50 deg. seat, exhaust 313 @.900 with a 1.810 and a 45 deg. seat, this is how all the air flow wars start on web boards. Mike would you like a copy of your flow sheet ?

Your missing the point, people throw flow numbers out there and have nothing to back them up, we do and so do some others. If your not sure about something best not to make it up and mislead people. Its not a right or wrong thing also, flow benches differ, its a tool to learn with and make gains, that's all.

Some "hostility" here ?

Really just 419 from a ported b1 mc ?
Seems low to me, but I guess I'd be more worried about how well the motor ran.....
