3.0 V6 12v - play with valves and seats (Brainstorming) :)
Posted: Tue Nov 27, 2007 3:42 am
My friend is planning to modify stock 3.0 V6 12v heads, could you post some comments about these (for now, virtual) changes?
As you can see table, main questions are related to valves and seats;
1. I know that bigger-better is not always true, what do you think about increase of intake valve sizes?
2. Second is related to seats; Can stock seats be bored to support 46mm valve or we have to replace them with new ones?
Thanks for suggestions/opinions!
