After it was back together and I saw there was oil preasure issues. It all had to come back out. Take it out now and have the rods and bearings checked now imo.

**** man, i can't afford that, and then again can i afford not to, this is work thats done for me in a workshop, i'm a carpenter with not that much mechanical knowledge or the hoist & tools to do this.

Have just ordered replacement parts from TSP + N/W 96mmTB & Fast 102intake, they've quoted a 'Fast 102TB' though, i would rather the N/Wtb as i have an aftermarket ECU & don't wish tuning issues with the Fast 102tb.

Now my pockets near on dry & still have to pay for getting it all fixed and retuned.

Lighter would be sodium filled valves which these won't be.

Maybe he got them mixed up or something. SS valves should be heavier than stock right?

EDIT: Nevermind, this fool was comparing the TSP valves to some old SBC valves.

Sweet as, this was comparing standed LS1 valves against TSPs 5.3ltr stg 2.5 Have since been told by Trevor 'tsp' that they get theirs made for the heads,

I have no idea what difference there is though
