I have Questions…If you feel like responding cool, if not, ok.

Things in the forum I’ve read and wondering about.

- For +1 valves does the head have to be machined bigger?

- What is a +1 head?

Thanks, I might have some more.

a +1 head just means it has +1 valves I think. Not sure on your other question.

the valve seats have to be cut bigger to accommodate the larger valves if they are +1, +2, or +3.
