If you are running 180° i'd psi test cooling system. Leakdown=Plug both exh. Holes & both intake holes. In 1 or 2 of the plugs, put a shrader valve and a low psi. Gauge in the other. pump up to 7 psi & it should hold for 7 min's ...iirc You can just use pvc pipe with a "T" & caps & put them in the intake boots, with OG clamps. you'll just have to use the open part of the "T" in 1 to put in a shrader & a gauge in the other 1& rubber expansion plugs in the exh.

Define "all" have you checked the actual temp's? Done a leakdown test? Sent from my SM-A505U using Tapatalk

Verify its a 4mil. Crank Verify piston #'s If pistons were wrong, the cheep way is buy correct pistons & try & get it running & Reassess. Better solution ~send to reputable builder get correct porting, check crank & ditch the spacer. Sent from my SM-A505U using Tapatalk

You probably went in farther than it usually goes. They're typically spring loaded, it might un-stick but i'd try & pull it back out ( with fluid in reservoir)before pushing it in farther & when you bleed it, only go in1/2 way in each time, until it gets some psi built up.

I believe they're all the same . are you having a fitment problems or just notice the bolt looks different. when they're tweaked or aftermarket radiators, there's a sequence to install it that helps. I forget what it is.. start at the bottom left or something like that... maybe somebody will chime in Sent from my SM-A505U using Tapatalk

@bansheehp

You can get 100+ hp outa a stock cylinder. How you get there and what its good for are 2 different things. Going off a video doesn't make much sense... but to each their own Sent from my SM-A505U using Tapatalk
