If this is a high RPM motor, then it's also a high overlap motor, the exhaust flows very well for a reason, and that's to help exhaust scavenging at higher RPM. The overlap period is nowhere near max lift, it's like .150-.200 just something to keep in mind.
I still think this won't take more than a .600 cam, so as far as the intake you're almost there. You think a 50 degree seat would help top end flow a bit, or are you sticking to a 45? There might be a few CFM hiding in the valve seat angles.
@@rickyfulks6656 I have no idea. They were completely raw and the customer had the guides, bolt holes and spark plug holes drilled...very expensive work right there.

Great info.
@@brokentoolgarage Thanks!
Good work!
@@65mustang393 Thanks!
Does the high angle port has beter flow beter cfm and less separation than low angle port like this head?
@@amirdoshmanfekan5145 High angle if I understand you like a 9 degree Chevy have a much more upswept port that flows better.
The valve job looks nasty
@@rickkelsch2040 You wound me deeply.... it is as high as I can do because it may get different valve sizes! Thanks
@@servediocylinderheads I am sorry, I just think a really nice valve job would help the flow
@@rickkelsch2040 The nice valve job is after all porting...thanks

@@rolandotillit2867 Customer wants a 45 so 45 it is. Thanks
IMO the cam should lift .030-.050 more than the head peak flow point.
More area under the curve at all midlift points.

Do these castings have a different port design Charlie?
@@rickyfulks6656 Yes they do. Thanks
@@servediocylinderheads I'm 65 Charlie n I have been unaware of these casting. Learn something everyday
@@rickyfulks6656 As it should be! Thanks
How difficult and expensive r these castings to aquire Charlie?
@@rickyfulks6656 I have no idea. They were completely raw and the customer had the guides, bolt holes and spark plug holes drilled...very expensive work right there.
So close it could go 500hp just barely
@@No1414body Stay tuned!
