Hey Go Tech guys. I'm thinking of trying one or both of these engines.

But before I switch from Novas, got a few questions.

I like the 421b type power, though I have a couple of P5s I run as well. What kind of pipe do you recommend for the 7 port?

Are those of you running noticing a major difference between the turbo version and standard? What kind of plug is good for standard and turbo?

And last, is the Go Tech head bolt pattern the same as any other mills so a guy could use an aftermarket head on it?

Thanks in advance guys...
