I have been looking at the BMF 405 and dart has a new pro1 380.And are the rhs 360 heads any good.The engine will be kept below 6500 and will be close to 15.1.What heads would you recommend.Thanks.

I was also wanting feedback on the merlin x intake.Is it better than a super victor.

Also a REALLY good head for 623's is the Dart Big M CnC ported, .
or the Dart 360 cnc ported to 385 cc, . .
that's if you don't use spread port heads, .

The Edelbrock Super Victor will smoke the merlin intake, ..

the ProFiler Sniper intake would be another good choice, .. ..

Would the rhs 360 heads hand ported work very good.Or could you recommend any other heads as cast that would be any good.Thanks

cboggs

The only as cast head that would be close would be the Dart Big M
at 410cc, ..

Thanks for the info Curtis.

I noticed BMF was mentioned. These seem like a great head for the money. 385cc fully CNC ported for $3300. What do you know about these?

the new edelbrock cnc 380 head verses the bmf 385. Is there going to be any advantage of one over the other one on the 598- 632 ? Im asking for the boating application i talked to you about the other day. Not mainly for dragracing but up to 7200 rpms or so when drag racing. You talked about cross section the other day and now i want to know about the bmf 385 compared to the cnc'd dart 360 and 380 edelbrock. thanks

BMF said the valves in their heads are manley racemaster and the severe duty is really not needed.I always ran the severe duty valves and was wondering if i buy the heads should i get the upgrade or are the racemasters just fine.I called shafiroff and they told me the BMF heads they sale are assembled by them and they put the severe duty valves in them.Please give me some info on what to do.

The CnC Edelbrock will smoke the larger port cross section of
the BMF or the Dart head. It has a better air speed for power
and torque needed in a boat.

Cheers,
