Many thanx for the quick replies Guys!

The port work and pictures are truly AWESOME!

Very interesting your comment on 518 to 286 Max Wedge ports?
I am fortunate to have a set of 62 286 heads and the ports are awesome lol.

There were a lot of trick iron headed 440's here in the 80's and 90's.
But the evolution of Aluminum has pretty much 'killed them off'...

For me I want to run in a kinda 'Superstock' set-up with a six-barrel on my 71 GTX.
Its a Canadian car with 346 heads and the engine is BLUE?

The car was raced in the 90's and has succumbed to rust issues.

After a 20 year resto I want to get her back out, with another 440 or 511.
Sold all my Ali heads but have a few 'old school irons' laying around lol.

Gonna practice on some ex Jensen sixpack 902's for now with a 3/8 inch manifold spacer.

ps, my old 452ci iron-engine used to rev to 7200, would have gone more but I didn't want to wreck an ex 69 SP Superbee block, (now back in the car)!
