I've got an engine with a NB2 short-block, NB1 head, shaved(forgot how much, it was warped quite a bit though), 5-angle valve job, bowls polished, and a slight port job. I'm planning on putting it in after this season of auto-x.

Doing 949's recipe of EUDM square-top, MSM intake cam, tuned on a MS2, 12-tooth crank trigger from TSE, IAT in for MAF, I/H/E, straight 93 pump-gas with an second 110 octane tune(yay for the South and it's local dirt-tracks and dragways).

I'll be happy if I make 140rwhp on 93, who knows with 110, may not even be that much of a gain. But I figure it'd increase the longevity on the engine, were all on borrowed time when we track a car anyways, right?

Dynoing 11.5:1CR, 99 head, knifed crank, RB header, and square top intake plenum later today.

Stock or ported head? Shim under buckets?

Flier, I'm going the same route, how have you made out? I'm going to be looking for quotes from some local machine shops to port my head and source a square intake. Wonder how yours went?
