I am sure that is a miserable job, trying to fit all of that in such little space. hats off to you.

I dont know what the other specs are of your engine but it doesnt look like you will be able to remove the valve covers without removing the exhaust. That would really suck when you need to adjust the valves and I dont see how you will access the plugs either.

not trying to but I have considered building headers and never grown the cojones
