M2 Heads

[blackstangs]

Has anyone ever used a set of heads ported by M2 Race Systems. I am building a 347 with Brodix Track 1 heads, they were ported by M2, bought car and engine not finished, M2 cant give me any soild info on what kind of headers to use. A stock 302 header is too small due to port job. The orignal exhaust bolt holes have been welded up and new ones drilled and tapped about a half inch further one each stud. I'll try to post a picture. Any help would be great.

you need to buy a set of headers with 3" inline pattern. I had a set of T1 M2's few years ago. Nice heads and port work. On the end of the head/s it should have T1M2 stamped on them.

the new pattern is prob 3in on center, measure it.
m2 does good work
i ported a set of track ones and its pretty easy to get over 300cfm

Thanks guys, yes from outside hole to outside hole is three inches. Does anyone make a set or am I going to have to buy a set of 3 inch flanges and make them.

kooks has sets and you can also buy the flange.

i believe the 2 3/4 center to center is the n351 pattern.
kooks, accufab both make them.
i might have a set of flanges if your gonna modify a set or make your own.

If the op doesn't want the flanges I would like to buy them .
