Eddy heads on 416 stroker question
The heads I will be using next were bot from MRL and had the springs I bought for the cam installed. I basically let Mike work out what I needed to copy a build he posted here including the cam and roller lifters (a 418 which also has the 20 cc dish pistons I have in the 416). Bot Hughes 1.6 rockers and sent them up to him to clearance. This worked out pretty good. Only thing I might have done different is pay to also have the rockers put on the shafts and the shafts installed on the complete heads, ready to install.
The OP got his money's worth of free advice from this forum on the chambers. Good catch.
