Is anyone aware of an adapter that will allow use of cleveland style header flange to be bolted to windsor style (inline) exhaust bolt pattern?
I have seen three different bolt patterns on windsor heads...unless my memory is faulty.
the dual, inline pattern...which has the normal width and a second set of bolt holes, wider set...making a total of 4 bolt holes on each exhaust port.
then a set which has the rounder exhaust port with cleveland style bolt pattern (set on an axis) off the top and bottom of each port.
This is for a short deck (302) type block.
A while back there was a thread that mentioned the existance of a flange which uses counter sunk bolts to convert the bolt pattern from inline (W-type) to axis type (C-pattern). I need to confirm who makes them, P/N and a source, if possible.
The only marking on the headers is "J 302", I have a set of the early "J 302" heads, but the patterns don't match.
I'm guessing I could have the heads drilled for the pattern, but I am not real sure I wouldn't hit water or if the surface would be flat enough to seal correctly.
Some of you guys that have been around longer than a minute might be able to give a hint on this.
