Inliners International Forums General Discussion Hi Performance 1.94 1.84 valves in "194" and 292 head w/pics

Here are pics of 1.84 and 1.94 in "194 and 230/250/292 open chambered heads.
It is hard to see. The 1.84 valve in a "194" head is spaced the same as a 1.94 valve in a 292 head. These are untouched heads, no porting or relieving is done, yet.

Serious relieving of the Chamber is needed to make the 1.94 valve work in a "194" head. I have recently tried this on my Dyno 292 and the "194" head with a 1.94 valve is down over 10 hp @ peak and also down on tq across the entire rpm range. The head I ran had the same chamber relieving as was used on a simularly prepared 292 head with 1.94 valves. So my findings are "194" heads do not work well and to make them work is wasted as less work on a open chamber head results in more power for less money. In the images with valve open. Lift was apprx .500"
