pressure test 21 stud
 

Being lazy here and not digging out my pressure test equipment to see if it fits. So, are there enough common stud holes to get a good seal with a 24 stud pressure test block?

No.

Hey Hombre
Could you put a head on and check that way? Making the assumption that the block is empty of all internals, of course.

Kahuna, so good to hear from you. I've been so worried about you!

*inside joke*****

How am I going to spray soapy water around the valve seats to make sure there are no cracks? But, you gave me an idea. I will see if I can get an old 21 stud head gasket to use as a pattern to get a pressure top cut out.

How about taking an old head and cut holes over each cylinder? Make a gasket with no water holes and you have your test plate.

Which could then also be used as a torque plate for boring

Hit up a High School Industrial Arts teacher. Scout him out on the web. A LOT of those guys are on the take. His scrap plate or yours. The plus is you'll contribute to some student's vocational experience which is always a nice good deed.

I currently only have one 21 stud head for this prospective engine. I have a lead on another in the swapmeet section. So, 21 stud heads are a little more scarce than 24 types so I don't have any extras to be cutting up. I like your suggestion, Lonnie, and thanks to all for the others.
