I'm sure there has to be other things done as well to get the desired results. Does anybody know any thing about this?

There were different heads made for the 194, so check the number before you pay for one. I believe the Inliners web site has the part number list you will want. You might want to get a copy of the Power Manual wrote by Leo Santucci, it has a lot of information on the 250 and 292. Mostly racing stuff, but a lot can be used on the street.
The 194 head with 1.60" exhaust valves with mild porting will make a great head for a street 250. Get a mild camshaft to go with it. You should end up with 9.3 or so compression.
You can also get the same or better results with using 307 CI V-8 pistions. These pistions will give about 9.6 or so compression, maybe a bit more or less depending on the condition of your head. | | | | | Joined: Apr 2002 Posts: 1,571 Shop Shark | | Shop Shark Joined: Apr 2002 Posts: 1,571 | The 307 pistons won't work on the 292. Propane pistons are available. The 'performance pistons' thread in the Engine & Driveline shop has more info. Also...get the Santucci book -- it's your friend. | | |
