Hi all,
I'm doing an in-frame rebuild. Was planning on this for a couple of years as the compression and leak-down tests indicated that it would soon be necessary, plus a plug that fouled every 6 months. The decision to start the job was hastened after blowing the head gasket, haha.
So I have the head off and was planning on all new valves, guides, springs. My question is about seats and cutting or grinding. How do I know if I need to replace the seats? Can I leave the current seats in and just cut them with the fitted Neway cutters? Then just use the new valves? Do I even need to do cutting? Or can I use the grinding compound and do it that way to just clean them up? I'm taking the valves off this weekend and so I'll see what condition the seats are in at that time, but I like to know what to look for. I am finding so much conflicting information online that my head is spinning and I'm looking for some guidance here.
I greatly appreciate any insight, Thanks!
Chad
