Yep the hydraulic lifters take ages to fill up again, especially after they've been cleaned. Sometimes an hour or 2.I sold a pair of HKS high lift cams that came with a head I had donkeys years ago. Apparently the chap I sold them to really struggled to get an acceptable idle I think once you get rid of the flappy MAF and start running your own ECU you'll really get the best out of those cams.Looking good so far.
Are you going to get a throttle body from an auto? That used to be the cheapest route to get a variable TPS.Good luck at Cadwell.
