OK I ordered the same pistons you are running. Decided to use the Hughes cam 238/
[email protected]” 109lsa, 104 intake centerline, cam came with factory style lifters but slow bleed version from Hughes to save some budget as it was a great deal. This will have decent .578’/.587” lift with 1.6 ratio Harland Sharp rockers (that killed my budget saved on cam and lifters combo) recommended to use with tf190 heads rockers with pushrod oiling on magnum block. Do you remember how deep in the hole these pistons sit?
