For a boost 427. Which do u think would be better ?

Whats the deck thickness on both ?

Anyone use the PRC 237cc CNC Ported LS Cylinder Heads before ?

The PRC's have a 3/4" deck so at that point, are you going 4 or 6 bolt per cyl. I'd go which ever is less expensive. Boost 427s dont need much for heads.

What do you mean boost427 dont need much for heads.

I was going to go 6 bolt but I dont think i need to now.
I was going for over 1000 hp power but now thinking of just 850-900 and later on. when i can get traction do new heads and more boost but over a year later
