just pulled out the cylinder head thinking all i needed was a head gasket. found corrosion on the head. do these hole looke repairable or should i invest in a new head. thanks
It can be welded but the chances of it being successful are remote.The head will eaten through in more than one spot,and up where you can't see it will be very thin creating hot spots.Buy a better head.
Toss that head and get a replacement. On the side of yours should be a part number, not to mention a compression rating. The compression rating is something like "e x.y". Nothing wrong with getting a higher compression head. -CTH
Your aluminum head can be welded & resurfaced if you can locate a machine shop that still does that kind of work. In years past I have see much worse damage repaired. Years ago (late 70's) there was a business that rebuilt aluminum heads. (in the lower San Francisco bay area). They would carve out the damaged area until it could be welded back with enough solid material. I don't know anyone with that skill today. But if you get caught between a rock-&-hard place (with no parts available) you can J/B weld it if the head gasket still covers the water-jacket.
Also -- first check the head & make sure it's not too warped. Measure the thickness of the cylinder head to make sure that you don't shave too much off; there are specs for original thickness & minimum allowable. (and the straight edge measurement is both bottom AND top of cylinder head; so the camshaft won't bind.)
And that valve looks like it is up too far in the head; You probably need new valves.
