Bang tidy! (Since we're going all Keith Lemon!
)
So what did you actually do then? Match port the heads to the manifolds or make a straighter run for the gases into the engine or something like that? What are these going to be used on now?
first off we cc'd the port, they are 62cc's, we then talked about the port size and shape and opted for a wedge (ish) port with a volume of around 75cc's.
It is hard to justify the time that has gone into the heads, I'd say between Daves machining and welding and my time porting, theres over 20 hours in them
The manifolds were welded up and then match ported, theres loads of work in these and the difference in the route to the head versus a standard off the shelf manifold is night and day.
Only the dyno will tell but on the heads as they were the cam just wasnt working, power would peak at 5k, and then drop away.
Once dyno'd Dave will do the last drag in November, after that he rekons its stripdown time, and if the heads work, i'll no doubt be buying them.
