i was told to take the valves out of the head to get the head machined. is this true? that should have been my question before i started taking the vavles out. i went a bought a valve spring compressor. this was the shietiest thing i ever saw. first the thing i got with it to push the spring down didnt even fit on there right so i had to mod it a little. even then it didnt work right and i went to push the spring down and i scracthed were the lifter goes and i think i fucked it up cause the lifter wont fit into its spot anymore. wtf do i do?? can i sand it down a bit or not? please help. thanks

You do not need to take the valves out. You just need to take the camshafts out because the valves will close automatically and you will have plenty of space to resurface the head. That is what I had done to my 87 Turbo Supra.

Also by looking at the picture, I would say DO NOT sand it down because that could throw off the OEM clearences and I would not even try to put that togther.

when i got my head machined i didnt take out the valves or spring or anything just got it down to the cams and they did the psrings and valves for me and put them back in too, so maybe you dont need to .

Let the machine shop tell you what to do.

Any decent machine shop will take a head with the cams still bolted in even with the cam gears still on. They will take all of it off so, like stated, the valves will be closed allowing for the sealing surface to get cut. They will replace the cam seals, torque all the caps to spec and make sure they get installed into their original order.

I would just take the head as is to a good machine shop and have them figure it out, they will let you know if you need a new head or not, my guess would be the head is fine.

yeah i took the head to a shop today and they said they will see what they can do about that problem (he said they will tey using cheese cloth) im getting the head maged and milled and possibly a valve job which comes to a grand total of $400 for the head to look like it just came off the factory assembly line

just got the head back today. cost $400 for a mag and mill and then a valve job

taking the block in next week

there is still a little gash do think it will effect anything? (second pic)

Have a better picture of the "gash". The surface looks a little rough, if you're going with an OEM HG it's fine if you're going MHG I'd lap it.
