Question

BEEN looking at vorteck heads and sr torker heads for 305 stroker. My question is what ics the biggest cc can you get for the heads on a 305.. My stock heads are 58cc casting numbers 450. If im not mistaken the sr torker heads are the same cc What does that mean and what will is the difference betwen the 2 heads. thanks!

The stock Votecs will need different springs if you get wilder on the cam, and adding srew in studs will help. But then you have the special intake, and self aligning rockers. The S/R's are already done, and you can use any older style rockers and intakes.

Count my vote for the S/R Torquers with 58cc chambers.

I'd have to agree with Tracy! I priced out the vortecs and it's about $700-850 for em with the special intake and rockers and valve covers (it's like $600-650 for the intake M and heads I think). Then add better springs and screw in studs. I think Dart may also have some decently priced heads for a 305 not sure though. The local head shop (one of the ones the dragsters use) recommended the iron Darts and he wouldn't have made anything off me to boot and knew it.

I got a set of the torquers and there is some advantages I was'nt aware of. I put a set off full roller rockers on, and the stock valve covers cleared to my suprise. The higher rails is what did it I think.

Kevy,
I like the Comp line of cams. If you want a nice torque cam, with a nice lopey idle, get the XE268.

Thanks guys, I appreicate the info. Does anyone like the elderblock carburetors. IM new at this and I want my set up to work good. This is the plan so far let me know if its good or what well help. The block is at the machine shop now. He boring to 30! and putting in freeze plugs and cam berins. I called him today he said the vortech will work but not with 202 valves. have to go with 194 and change the springs. I found the kit to make it a stroker waiting on the catalog to come in. havent made up mind with heads yet. VORTEH OR SR TORKERS!,biggest cam to be put in with very nice chop. not to big to hurt my power. dual plane carb,and 750cfm. Will be running 411 with positve . on a 3 speed manual on coulm (that will be put on the floor). Like I said this is my first one so any Info I will very much appreicate... Thanks again guyS!!!!!!

If you can get pistons to keep the compression at around 9:1 with the 64cc chambers I would go with the Vortec heads. The numbers show that they flow better. I have read that adding larger than stock valves (i.e. bigger than 1.94/1.50) to these heads will hurt flow and would not work with your 305's bore anyway.

The 305's small bore tend to stifle the high rpm flowing rate, but it will still make respectable power with the heads and the stroker kit. As for a cam I would go with a Comp Xtreme Energy grind, probably the XE256. This cam will offer good drivability and some good power from idle up. If you engine originally came with a roller cam, I would go with another roller cam, but if not check into Comp's XE line. Good luck.

HEADS: I just came from the machine shop and we got on the subject of cylinder heads: Quoting the machine shop owner "I can have or build any set of heads I want, and I put on SR Torkers." - and no, I wasn't buying, he's building a # match for motor for me & knew he wasn't selling me anything. PS: Keep 1.94's- they'll make more torque over 2.02s. 2.02 add top end HP, but only if you CONSISTENTLY live in the 5500-6500rpm range.
CARB: As for Edelbrock carbs, I've put them on 3 different cars & finally talked my neighbor into dumping his Holley 4110. He says its the best his car has run in 7 years. My opinion - If not # match, then its edelbrock!! Highly recommended.
