Lots of performance parts on my LA 360 - let's build my Magnum / Stroker

My goal is a to have a 408 Magnum Stroker with EFI - I'd love to hear everyone's thoughts on what I currently have and what can be transferred to this new engine. This will be a 98% street car. I'm trying to bridge the gap and come with a realistic budget but it makes it interesting since I have a fair amount of transfer friendly parts.

Builder engine: - 2002 360 Magnum - M1 Dual Plane Intake (Magnum)

Current engine: - 1976 360 LA - M1 Intake - HEI Distributor - EQ Heads
Current trans - A500 with 9.5" 3200 stall converter
Current rear: - 8.75 (742) with 3.91 gear (245/45/18 tire)

Wishlist: Scat stroker kit - EFI

• Previous owner installed a set of 2.02/1.62 EQ heads on the LA Engine drilled for LA intakes. I assume these will transfer without issue.
• Previous owner had a custom Comp roller cam ground on an LA blank - specs are: 224/230 .050" and .513 lift I/E on 110 LSA - ground for 1.6 rockers. Would this be good fit for the 408 Magnum? Any issue that anyone can foresee?
• With the roller cam, he also opted for a set of retrofit Hughes LA roller lifters ($$) - can these be used in the Magnum with the EQ heads? Or would I be better off using the OE lifters here?
• I have a pair of M1 intakes - I'd obviously use the LA style with the EQ heads - is this an adequate intake for my plan or would I further benefit from a RPM Air Gap or other suggestion?
• Current engine has a Coyes index timing chain - will this transfer to Magnum?

If you need any other details to clarify anything - I'll report back. Bare with me as I'm a bit green to this process - thanks.
