Damn Mondays.............
Spent some time porting the split-port heads today, didn't go well. I got greedy with the carbide cutter and ground a nice hole into the intake port coolant jacket in the bowl area. Not like working on old cast iron heads like I'm used to.
I welded it up, but it's just too far gone to be trusted so I'm out $100 and about 16 hours of my time spent on it. At least on the bright side I can now cut it up in the bandsaw and get a much better look at the ports which I kind of wanted to do anyway, just not with this set of heads.
Which means that I am now left with some choices to make.
A. Buy another split-port head, modify the fuel injector locations to match the other head.
B. Shelve the split-port/M90 part of the project for now and use my existing set of SC heads and design/make a new lower intake manifold for it to use with my new upper plenum, the one with the cobra throttle body spot that says turbo on it.
C. Buy another set of split-port heads and another intake manifold. Make a new lower intake adapter that will work with a stock split-port setup and the M90. Basically Split-port/M90 project rev. 2.
A and B are the least expensive but C would be the most fun. Not sure which way the wind is going to blow on this, probably A or C.
