I have a stock 292 in my truck right now, and a spare 250 sitting in the barn, could I put the 250 head onto my 292 to boost my compression ratio or is it a waste of time to even think about it? | | | | | Joined: Aug 2008 Posts: 230 Shop Shark | | Shop Shark Joined: Aug 2008 Posts: 230 | cant tell you how big the cc's are in the combustion chamber's but i took a 230 head and droped some v-8 valves and put it on my 292 and it run's fine .i used it because that was all i had . | | | | | Joined: Mar 2004 Posts: 874 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 874 | The 194/230/250/292 are the same family and the heads will interchange. The 235 is a different animal.
I think only the 194 head has smaller combustion chambers. | | | | | Joined: Nov 2002 Posts: 1,002 Shop Shark | | Shop Shark Joined: Nov 2002 Posts: 1,002 | Ghostrider has it right. The only head that will get you a compression increase is the 194. The 194 has a 62 vs 72-78cc combustion chamber. That's before any valve or porting work is done. The 194 head will up your compression by about a point, your mileage may vary. Check inliners.org for head casting numbers.

It still runs well on 87 octane, and goes like a scalded cat!

I will definitely check the casting number on here before I buy anything  Any idea about how much it costs to have the valve/porting work done? | | |
