Hello. I have been thinking of epoxying the intake and heads on a 4V Cleveland. I called around today, and only one machine shop had any exp. with epoxy. They suggested Moroso A+B. Anyone on this board have any exp. in this area? How much do you fill? I was thinking about 3/4" at the head entrance. How many packages will it take? Do you fill all at once, or in layers? I figure the head has to be very clean and somewhat scuffed up. I also heard about using screws to help hold the epoxy in place. Any input would be great. Thanks, Matt.
