    I’d avoid mmr. I believe JPC among others (even FPP has some listings) for those plates

    My intent was not to advertise for MMR but to point out that their narrative refers to aftermarket pistons hitting the squirters.

    Question about valve seating. With the valves setup with springs etc and the entrance to the valve full of gasoline, we see no leaks out of the valves on the combustion side. For an extra check, my mechanic blows compressed air at the combustion side of the valve, and if he has any bubbles appear it goes back to hand lapping the valve. So far all are ok except for one... Which he is working on now ... I always thought you just check with a dye and are ready to go. Is this bubble check a typical method? maked sense to me, but wanted to check
