Hi peeps

I'm putting a decent engine together for my Sei and I have a P75 cylinder head. Trouble is the poxy rubber gaskets on the modern inlets are to big to seal on the head ports.

Has anyone fabricated an inlet manifold for any of the fire engines?
Did it work well? Do you have your plans?

Or my other option is to use a modern head. Which of the more modern mpi heads have the same inlet valve sizes as the P75 (31.5mm I think)?

Any help would save a lot of fabrication work.
(Got my 40mm throttle from Steve)
