Some more pics of the head assembly!

P90 back with all the work complete. Reg has the Colt Cam all buttoned up and rotating smooth, lash pads and springs. Hope to make some good power with this head. 

Looking good!

Almost ready! Rebello 3.0 stroker build. 

Am i right.. you must have 2 different pistons? (the indents on top are different) ?

No, they are a matched set from Rebello/Traum

The reliefs are going to be different depending on the orientation of the intake and exhaust valves in each cylinder.  Half are I-E and the others are E-I.

That's what i meant.. I and E valves are on diff places so watch the orientation.. As Jeff said: half is I-E and the others are E-I.

I guess Rebello already had numbered the pistons, so you only have to put them in the right spot.

Btw. did you know that Traum in german means: dream?  those are dream-pistons! 😃

, dream pistons.
Yes the engine is properly assembled.

So this happened…!

 

Which led to this….

 

He makes a beautiful exhaust!!!
