Hi Guys,

Almost got all the bits to have my new race motor built. One thing I do need are head studs in 10mm size.
Brief engine spec is 2276cc, fk89, wisecos, comp eliminators 48x38, IDA's and 12:1 cr

What do you recommend?

I'm using the Scat 8mm studs for my 94mm barrels.  I think they're easier to fit than the 10mm.  I'm going 10.5:1 c/r, and will hold just fine.

While Raceware is a very nice and stout product, there is no need for them in such "mild" engines. Std CB/Scat 8 or 10 mm studs holds up fine up to about 12,5/1 CR with an FK89 and similar in the 230-240ish range. With turbo or nitrous of the serius kind Raceware is the ticket.
The CSP stud kit is ok. I dont like the nuts, and always replace them, and use the CSP nuts for rocker arms etc.

Are the 10mm original studs good enough the Red Baron I guess they should be good enough for most of us?

OG studs are fine. I use the Raceware's on mine but they are turbo motors. I'd go with ARP nuts with the OGs.

OEM stock 8 mm until which are pretty good if new and not corroded plus not tightened mor ethan stock.
Then I started buying at Raceware from Randy Hubbard in 1994. Quality and excellent service in combination.
Never looked back.
Both headstuds and through the block bolts.

Same here, Scat 8 mm studs and nuts, with JPM 48 x 37 heads, 10.6:1 CR, 94 mm Mahle cylinders (slight trimming of the grooves required to clear the studs).
