6.4 head work ?

Jayz · Jun 7, 2012

im fixing to have head studs installed,guy doing work said he doesnt send heads out to be resurfaced. As there is only .03 thousands to work with and to make them flat again usually takes about .05 thou and that would make pistons hit heads. IS THIS TRUE? Just wanna make sure hes not blowing smoke,he seams to know his stuff but just want a 2nd opinon from y'all. thanx guys

The heads can be decked and you'd be stupid not to. Heck I decked my block 7 thou and was still well within spec even with decked heads.

I'd take it elsewhere.

.030 is a lot of material but I don't think the ford spec has that much iirc. When I looked into it I think ford allows .010 to come off? Unless your heads aren't super warped most heads only get surfaced .003-.006 to get the flatness in check. Maybe you misplaced the decimal?

Ya. You can take quite a bit off the heads but it requires resetting the valves in the head and adjusting the valve stem height to match the amount taken off. I'd take it elsewhere. It's been done by not decking them but it's not advised.

At least send them in to get checked. The amount of money you spend at a machine shop is no where near the cost of having to do a gasket job over again.

Where are you located

I from personal experience recommend decking the heads. I did mine first without decking with black onyx gaskets and only lasted 4 months. Pulled heads they were warped, took 8 thousands off put oem back on and been great ever since!

If the heads come off, send them out to a machine shop forsure. Have them checked for strightness and cracks. I would not do a head gasket job without being sure the heads are good and stright with no cracks.
