Yes I do believe I know who, but your right its none of you business or mine to display here, I know for one that they are not being done by one person! Your right, I have never have ported TA's cylinder heads, I never said I did but I can see where some improvement can be made and I bet several have done it already. I just wrote Mike JR in private message, there is no need to discuss this part any more. Both Mikes done said "they are producing products for the average person not the all out racer. I get what they have said and want to leave that area alone now. I was wrong for what I did and I apologized to them both already. Just think now, you all said Buicks are for the gentlemen, prove it to me by not continuing the wrongs I have commented. Like I said, There is room for improvement (SB2.2 Cylinder head Deign) But that is for the all out racer, not the average Joe! Now, please inlighten the folks that don't know where to port first and fore most, the most... Sincere Gary M.
