hello,
picked up a pair of "452" b/b heads for my stocker, has a 1/8" pipe plug on one end. is this factory? motor home?? never seen this before. also appear to be surfaced quite a bit, casting numbers on deck surface top 1/16th have been machined. deck thickness on lower head bolts is 1.00 thick, what's unsurfaced thickness?
all parts are sold as is, all parts are considered used no warranties or returns

What kind of spark plugs do those heads use? I’ve heard that uncut heads measure a little over 1”, but I’ve never measured personally

906's usually measure 1.00ish from the factory ,I never measured the set I had gotten from Paul Rossi back in the 80's , they were NOS castings , small plug with the water ports around the spark plugs.
What's the depth of the open part of the chamber , the set I had were over .100 , as deep as .130 in the center of the head.
running up my post count some more .

The 1/8" pipe plug is factory and I believe to be only on motorhome heads. I just sold a set like that a few weeks ago. I removed them from a 440 that came out of a motorhome.

regular spark plug no taper, no steam holes, chamber depth measures .063
was there a calculation for surface milling for cc reduction?

The outer head bolt row is usually a reliable indicator for head milling.
Uncut heads will be right about 1.00” thick.

was there a calculation for surface milling for cc reduction? .063 says to me it's been cut , I've never seen an open chamber head that shallow... is the open part of the chamber floor parallel to the deck surface ? That almost looks angle milled , which I've never heard being done to a big block wedge head?
running up my post count some more .

Starting to sound like these are some type of motorhome heads. The 452 heads I used on my 440 doesn’t have that boss drilled and tapped. It also took flat/gasket spark plugs
