J head porting

Just getting started on a set of 1972 j's, milled the guide down .200 and about to profile the guide. was there a long thread about porting j/x heads? I can't seem to find it. anyway, can the guide tail be removed completely? This will be going on a somewhat stock appearing 6 pack, intake has been deep port matched. I know aluminum heads would be much better but the 6 pack intake don't flow all the great anyway, plus the looks on their faces when they see they got smacked by a SB with stock heads is fun.
Pittsburgh racer sent me this old article.
The 6 pack flows a lot better than you think and a deep port matching helps a good bit on any intake. You can one up on the intake by making sure the throttle bores are the same size of not ever so slightly larger than the carb size is. Then stick your burr or cartridge roll in there and contour what you can under the carb.

I’d bet 23 years later he wouldn’t use a 30 degree seat. If he would he is way behind in his thinking.

Shape matters more than flow. Way more.

Agreed! Even more so after he got done learning something from David Vizard.
