The pistons are below deck so I don't think there will be any clearance issues. They are 30 over pistons but seem to be stock replacements. Just getting the heads cleaned up and surfaced. Not doing anything to reduce the deck height other than the surfacing. Just a surface, springs and exhaust valve change. The block also needs the sag taken out. I don't think the amount that needs to be removed will be that huge.
Bad B..
Yea the K6401 cam isn't that radical. Its actually used fairly often on low compression engines. Lets say for instance a 77 Motorhome 440.
