SB Pro Comp Aluminum Heads...For Sale on Ebay..

Not that much cheaper than Edelbrocks.

Advertised flow numbers are very close to Edelbrock advertised numbers. Seems like a copied head from China?

So I guess the difference they are trying to sell on is mrperformanceparts' machine shops valve job.

I guess I've never heard of that shop. I would put more value to an IMM package at the same price.

Still think for a Chinese head that has the same Edelbrock flow numbers, I'd like to see a consistant $300 or so cheaper than a USA made head even with personal machine shop valve job.
