Yeah, i remember you commented on another thread about the headgasket issues. I'm shooting for 600-650 whp. 93 octane (we don't have e85 where I'm at). Is there any remedies to help? Specific headgasket and/or specific ARP bolts?

My natural choice for compression would be 9:1, but I'm getting mix info about staying 11:1 for quicker spooling or 10:1 as a middle point between 9 and 11. Any input on this? I will most likely go with Z1Motorsports' Stage 1 or stage 2 rebuild kits... unless anyone has any recommendations.

Much appreciated!

For your power you can stay at 11:1 but that will limit you in the future if you want more power. 10:1 is the lowest I would go. Since you are doing pump gas, 10:1 would be your best choice. The rest is up to you. I would recommend you call Mazworx and talk to Mark. Let them assemble the whole long block.

Ethanol would benefit more with a lower than stock static compression; as leaving room to dump more fuel
You can purchase high quality ethanol from Ignite Race Fuel & have shipped to you by the barrel
Especially when you want to dial up boost
Huge power difference vs 93
