Message	end. For cylinder heads, at the very least a cleanup / refresh. You'd be surprised how much cams help with spool up and top end power, even with smaller turbos like 530BBs. Of course, it opens up a whole new can of worms because you will need adjustable cam gears to take full advantage. For cylinder head gasket, go OEM. Even at 800HP+ power levels it is fine. MLS gaskets are less forgiving and if your surfaces aren't machined perfectly, you can experience leaks with them. For turbos, go either with JWT 550BBs or 700BBs. GTX if the budget allows. 550BBs combined with Ashspec 2.5" IC piping and intercoolers should net you between 450-500HP on pump 93. Most importantly, get a proper custom tune done. You can bolt on whatever you like, but it is the tune that is going to make everything work well and operate safely.

However, those 550s you have are not very good - MixManMash 20:37:03 05/31/15 Yeah I know they aren't great, - platinumist 00:04:21 06/01/15 I'd do a leak down test - aliaZ 14:58:33 05/30/15 Agreed. (n/m) - Bernie (NoVA) 19:39:06 05/30/15 Very good point and I agree. (n/m) - MixManMash 10:54:19 05/31/15 Good point. - platinumist 14:42:43 05/31/15
