Yes, but think you would be pretty safe with low km motor.

so its not so much how the block was manufactured its more to do with km and how hard a time its had???

budget $100 to $120 per exhaust valve, b series turbo heads new off the shelf from fraud are around $2400. Have you priced an Fg unit from your friendly fraud dealer? It doesn't take long (with a b series head at least) to rack up the cost of a new head converting an NA to T</p></blockquote>

Yeah FG heads are same price..

Seats in N/A head are the same as Turbo, but Exhaust Valves are different as they have to take a lot of heat when opening, and this heat has nowhere to go and is absorbed by the valve. The heat is transferred to the head when the valve closes and makes contact with the seat. Budget of around $100-120 for each Exhaust valve depending on make and quality.
