New KB Pistons

[1FSTRK]

So now that we are switching heads, what are the sizes on the Manley valve heads and what do they flow?

Also, why is a 280 cfm head too small for a 110 drop in kit?

My findings on Raised runner is, you don't need to with a 1.9 valve. I can get mid 280s @28" without raising the port
roof on a 1.9 valve. (I'm getting 280 with John's 1.875 valve and leaving the guides in the head)

Do you have any dyno sheets from engines with this head?

Sorry the intake valves are only 1.85

F.K.

Noted, just makes the great flow numbers that much more incredible.
I would ike to see them on a 107 or 110ci.

Two different animals.

We haven't dynoed these 1.875 heads yet, they're for smaller motors (Just have flow numbers right
now). I'll have dyno information on these small valve heads soon, but they're going to be real close
performance wise.

(Smarty's 103 heads have Manleys in them)

I do

Any word on the dyno for these heads?

I guess I got off topic in my deleted post asking about the pistons..

So I guess these heads only flow these numbers with the KB pistons?

If you put these under your heads they will make great power
