[hondaman01]

now that looks NICEEEE

Thats no 450r head thats for sure..... Not sure I like the combustion chamber on that thing to be honest. Port job look pretty sweet though from what we can see!

EDIT: Doh, it says its a preditor... still dont like the combustion chamber...carry on....lol

 

[Venom501KingR]

One thing that I like that you can tell is its got 2 seperate exhaust ports. I think the honda would run better if it had 2 seperate ports. Lets take the combustion chamber of the honda and mate it to the predetor's exhaust layout!

that looks purdy

Loookin good :thumbup:

 

[poorboy]

That is very pretty. That's what I like to see in the exhaust port finish wise.

 

[prlandry]

The valves look very shrouded on that head.

i see a possible flow problem

 

[ZIPS-TRX]

Very impressive!

The intakes bowls look fairly deep, more port volume. The exhaust bowls are very shallow.
Making a sharp allmost imediately.
Also note the bridge that is between the intake and exhaust.........just enough to increase quench yet not to much as to restrict overlap flow. This brige will also increase swirl and still leave enough room not to shroud the valves to much.

 

[travis fulton]

this port was supposed to be used for a low comp motor with a heafty shot of n0S
