Need Help on Magnum 360/380 hp Crate Motor Tech Info

Bought a 300hp 360 crate engine last January...Used with 15k miles on it. Been sitting in guy garage for years. He had partially disassemble the engine. He had changed out the stock pistons for KB362 pistons and Eagle SIR rods. He rebalanced the crank but nicked a rod journal putting the engine back together...So it sat....

I had the crank turned...had the block hot tanked and new cam bearing and honed the cylinder....Short block has been reassembled with new rings and bearing...I have the 380 hydraulic roller and a comp roller that is one size smaller...224/230..110 with same lift as mp cam.

Have not had a chance to check out the heads yet...look like standard magnum heads with upgraded valve springs.....Been thinking about getting EQ heads....but no decision yet until i look at the stock heads.
