Mild 340 build runs hot

John Trickler said
I have a mild 340 build. Stock bottom end, 30 over, Hughes whiplash cam, Eddie heads and a Summit knock-off Air-Gap intake, FAST EFI. It runs hot, 215-225 degrees. Last fall I tried multiple thermostats. Currently have a high flow 180 degree in it. Running CVF Wraptor serpentine system. Way big BeCool radiator. Radiator and 2 Spal 1522 fans, the radiator is doing the job, heat temp gun shows that. My question, I don't remember which head gasket I used, would have been a Fel-Pro though, is there a difference in the head gaskets orientation? Front to back? I am about ready to start tearing apart the engine to look for a problem, intake first.

I may be way off base here, but I fixed some overheating issues on a couple SB chevys by installing a spring in the lower radiator hose to prevent it from collapsing. On one of the engines, I could barely see the radiator hose collapsing, but it was and the spring fixed the issue. They all used to come with a spring, not anymore. Just a thought before you take it apart.
