Compression tested fine. Valve seals bad. Valves were also rattling I found out. Located a set of 302 heads with bigger 1.88/1.60 valves put in. Waiting to pick up. Will port them. Also found these Hedman headers for a good price while I’m in there. Plan to port match my performer intake as well. Looked into options of eventually running FAST series, but decided would have a separate and dedicated build for that with a 340. In the meantime, gonna see what this 318 can do.
