Time travel


I´m exploring a couple of areas more or less unknown to me, Mechanical fuel injection and the very tideous project of bringing a set of heads to birth. Basically MFI is the only righteous FI option for "Mother" and my approach is to listen very carefully to individuals who has proven it´s functionality with time slips and speed performance, and Hilborn has been very nice and responsive.
The Heads is another story and it´s been going on for years now, right now I have all critical dimensions and patterns set and checked and then checked again,  I`m also self educating myself in the CAD world and it´s not my day job so everytime I get back to it, it´s days of finding my way around SEKE´s, cordinates and views. But now I honestly think it´s time to make some shavings. With some help from Karling Racing I got the cubes of Uddeholm "Alumek" in the shop a year ago and the last few days I found some time (loooong hours) to verify height  dimensions for the rough machining to get it started. I posted a pic with a original dimension head in a same size cube rendered like glass (yeah I know it´s b.s.) but the Winterbrew tasted well when all dim´s where in.The final product is all about performance and basically 5/8" taller than original heads adressing the limitations such as spring height, short grip for valve guides etc  and the capability in todays CAD very quickly reveals the possibility for slightly less valve angles as the valve seat is further down.etc, etc.
Any decade now and it will be done. and if you wonder about the choise of material it´s easier the first time with Alu.  and two very heavy chunk´s of a secret steel matrix in the shed.......

This is very cool! Really excited to see the outcome. Raised ports I hope?!? and why not run Alum heads?
