Overhead valve

Post by RichardW » Fri Jul 17, 2020 12:17 am

Will any overhead valve head fit in 27 coupe without firewall modification?

Thanks

Richard

There is a version of a B Rajo where the back of the head is sloped to clear a 26/27 firewall.

Rajo's fit but the rocker cover is modified for the 26/7 fire wall. But the problem I found was they stink of oil fumes being open at the back of the rocker cover, removed my 4 valve for that reason.

Rajo also made the Model C35 to fit the '26 cowl without cutting into it. I have one, and the rear of the cover doesn't fit well enough to seal worth a darn.

I thought the four valve Rajo Model A was designed specifically to fit a standard firewall. The Four valve A will give you a much power as you need, they are plenty fast from my experience. JMHO
