Well I’ve certainly learned my lesson. I purchased a set of 2.0 heads off EBay and although both are the same casting. One is opened big, maybe for 106m cylinder. It has 8mm valve guides intake and exhaust valve sizes about 46mm and 40mm. The other head is stock; stock 94mm bore, 8mm intake, 9mm exhaust guides, and stock valve seats.
So I’m looking for a stock 2.0 head in decent condition with cracks. Thank you!
