Hopefully someone that ports Eddy RPM heads will chime in here and let me know how much meat is in the distributor area of these heads. I really removed alot of material today and it still was nowhere near fitting. I called Pertronix and he said they've seen guys grind an area of the distributor, they will still warranty the electrocics inside, just won't warranty the housing. So I ground on the distributor housing and it will now slide down and seat on the block but it won't turn to adjust timing, so I'm gonna have to grind on the head more, just need someone to make me feel better by saying that area of the head is super thick.

This setup is nice, billet aluminum, 2-wire hookup(and one power wire), adjustable rev limiter, good reliability.
But the fitment is a pain! And if I ever want to carry a spare it will have to be ground down also.

Valve covers seem to be fine so far.
