hey fellas. i took my ute in to put the new exhaust manifold on and get the exhaust straitened to fit. when put on the dyno it wasnt pushing any more than 125hp. turns out i need a rebuild. to the point.... i was thinking of jamming some forgies and doing the complete rebuild(go all out). was wondering what are some of your opinions on the type of pistons and rods i should use and what are best value for money. or is it even worth it. should i just be happy with the rebuild .

thanks in advance
