Is that the mutha thumpr or the 284 your referring to ? I'm match porting the heads to the manifold & bowl blending the chambers. I'm aiming for around 250cfm
Impressive,you have done your homework, mate. A well done 2:02 /1:60 ported head,should get there(expensive, it is). I always let the head porter choose the camshaft( just my opinion). Give the local machinist's some love,avoid the damn tariffs.
