okay so im going to build a friends YB engine, he wants to run a stage three 360ish bhp. Just wanted to know some info, is it best to go for ARP stud and nut kit for the head, also a wrc headgasket is a must but just wanted to know what gaksets you guys run, as ive had Cometic grpA before on a stage 3 and had no troubles?.
The head has had some work done, also Bd10 cams fitted so its probably best to get some vernier pulleys then.?
Thanks Retro.
